Description

Technical Field

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

[0002] In existing technology, the upper part of a flatbed sewing machine is a sewing platform, with the sewing head mounted on one side of the platform and the sewing section located in the middle. This results in a small space between the sewing head and the platform. In some cases, the fabric is fed forward from the sewing platform outside the sewing head; however, sometimes it needs to move forward from the sewing platform below the head, which is only suitable for smaller fabrics. For larger fabrics, passing through the sewing platform below the head during sewing can cause blockages, affecting sewing efficiency and potentially leading to sewing skewing and quality issues. Utility Model Content

[0003] To address the aforementioned technical deficiencies, this invention provides a flatbed sewing machine that allows large fabrics to pass smoothly through the sewing platform below the machine head, thereby improving sewing efficiency and quality.

[0004] This utility model discloses a flatbed sewing machine, including a base and a sewing head. A main unit is provided at one end of the base, and an installation platform is provided at the upper end of the main unit. The sewing head is provided on the installation platform. A support column is provided at the other end of the base, and a sewing platform is provided on the support column. The sewing head extends above the sewing platform. There is a gap between the sewing platform and the installation platform. A control pedal is connected to the main unit through a wire, and the control pedal is fixed to the base.

[0005] Several guide rollers are spaced apart between the main unit and the support column. Each guide roller has a mounting plate at both ends. One mounting plate is fixed to the main unit, and the other mounting plate is fixed to the support column. The guide rollers and the mounting plates are rotatably connected.

[0006] The control pedal is provided with connecting ears on both sides, and the connecting ears are provided with through holes. The base on both the front and rear sides of the support column is provided with screw holes corresponding to the through holes on the connecting ears. The control pedal is connected to the screw hole on one side of the base by bolts.

[0007] The flatbed sewing machine obtained by this utility model adopts a design where the sewing head is set on a mounting platform on one side, and an independent sewing platform extends above the sewing head. There is a gap between the sewing platform and the mounting platform so that large pieces of fabric can pass under the sewing head during the sewing process, thereby improving sewing efficiency and sewing quality.

[0009] Figure 2 This is a schematic diagram of the structure of the present invention. Figure 2 . Detailed Implementation

[0010] 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.

[0011] Example 1:

[0012] like Figure 1 , Figure 2 As shown, this utility model discloses a flatbed sewing machine, including a base 1 and a sewing head 4. A main unit 2 is provided at one end of the base 1, and an installation platform 3 is provided at the upper end of the main unit 2. The sewing head 4 is provided on the installation platform 3. A support column 5 is provided at the other end of the base 1, and a sewing platform 6 is provided on the support column 5. The sewing head 4 extends above the sewing platform 6. There is a gap between the sewing platform 6 and the installation platform 3. A control pedal 9 is connected to the main unit 2 through a wire, and the control pedal 9 is fixed to the base 1.

[0013] The main unit 2 is positioned at one end of the base 1, and a mounting platform 3 is mounted on the main unit 2. The sewing head 4 is mounted on the mounting platform 3 and extends to the sewing platform 6 on the other side. The sewing platform 6 is mounted via a support column 5. Preferably, the sewing platform 6 is at the same height as the mounting platform 3, so that a conventional sewing head 4 can be used. Both the main unit 2 and the sewing head 4 are components of commercially available sewing machines, and their specific structures will not be described in detail.

[0014] A gap is formed between the mounting platform 3 and the sewing platform 6. When sewing large pieces of fabric, and the fabric needs to move forward from below the machine head 4, the large pieces of fabric can pass through the gap between the mounting platform 3 and the sewing platform 6 without causing blockage. The large pieces of fabric move forward stably and smoothly, thereby improving sewing efficiency and sewing quality.

[0015] Several guide rollers 8 are spaced apart between the main unit 2 and the support column 5. Each guide roller 8 has a mounting plate 7 at both ends. One mounting plate 7 is fixed to the main unit 2, and the other is fixed to the support column 5. The guide rollers 8 and the mounting plates 7 are rotatably connected. The mounting plates 7 are located on both the main unit 2 and the support column 5, and both mounting plates 7 are at the same height. The guide rollers 8 are arranged at intervals between the two mounting plates 7 and can rotate freely. The actual height of the mounting plates 7 can be fixed according to actual needs. The gaps between the guide rollers 8 are relatively small, thus forming a support platform. When large pieces of fabric move forward from below the machine head 4, they can be placed on the guide rollers 8, eliminating the need to suspend them on the base 1 and thus avoiding significant tension at the sewing area. This ensures smooth and stable movement of large pieces of fabric with less resistance during movement, improving sewing efficiency.

[0016] The control pedal 9 is provided with connecting ears 10 on both sides, and the connecting ears 10 are provided with through holes. The base 1 on both the front and rear sides of the support column 5 is provided with screw holes 12 corresponding to the through holes on the connecting ears 10. The control pedal 9 is connected to the screw hole 12 on one side of the base 1 by bolts 11.

[0017] The control pedal 9 is a foot switch that controls whether the main unit 2 and the sewing head 4 are working. Normally, the control pedal 9 is positioned on the worker's side, with the sewing head 4 on the worker's left and the sewing platform 6 on the worker's right. However, different workers have different operating habits. For example, some workers are left-handed, so the sewing head 4 should not be positioned on the worker's right, and the sewing platform 6 should not be positioned on the worker's left. In this case, the control pedal 9 must be removed and installed on the other side, i.e., the worker's side, and secured with bolts 11 by engaging the through hole and screw hole 12 on the connecting lug 10. This allows the flatbed sewing machine to adapt to workers with different habits, allowing for easy adjustment and strong applicability.
