Description

Technical Field

[0001] The utility model relates to the technical field of sewing machines, in particular to a simple inclination adjustment mechanism for a feeding mechanism. Background Art

[0002] During the sewing process, the sewing machine usually works in the order of piercing the material, hooking the thread, taking up the thread and feeding the material. During the feeding process, the fabric is usually lifted and pulled back and forth by the feed teeth to achieve uniform and equidistant forward movement. After the fabric is moved, the sewing machine can proceed to the next sewing process, and the reciprocating cycle can complete sewing on the fabric.

[0003] In the prior art sewing machines, since the products to be sewn usually do not have too many special requirements during the production process, the height of the feed dogs is fixed during production. When the user needs to adjust the feed dogs of the sewing machine by himself, a special adjustment tool is required to adjust them. However, when sewing thicker fabrics, the feed dogs may easily be insufficient in height, resulting in insufficient cloth gripping force. At this time, adjustment is inconvenient and easily affects production efficiency. Utility Model Content

[0019] Optionally, the locking bolt is provided with anti-slip grooves, and the anti-slip grooves are arranged around the head of the locking bolt.

[0020] By adopting the above technical solution, anti-slip grooves are provided on the locking bolt, which can increase friction when the locking bolt is rotated, thereby making the locking bolt easier to rotate when the locking bolt is rotated, further improving the convenience of adjustment.

[0021] In summary, this application has at least the following beneficial effects:

[0022] The present application solves the problem that under the prior art, when the user needs to adjust the feed dogs of the sewing machine by himself, he needs to use a special adjustment tool to adjust them. However, when sewing thicker fabrics, the feed dogs are prone to having insufficient height, resulting in insufficient cloth gripping force, which is inconvenient to adjust and easily affects production efficiency. The present application provides an adjustment disk, which can drive the eccentric shaft to rotate after being pushed. The eccentric shaft can move the frame up and down during the rotation process, thereby realizing the height adjustment of the feed dogs and improving the convenience of adjustment.

[0029] The present application is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0030] A simple adjustment mechanism for the inclination of a feeding mechanism, such as Figure 1 and Figure 2 As shown, it comprises a frame 1, one end of which is fixedly provided with a feed tooth 11, and the other end of the frame 1 is provided with a clamping groove 12, in which an eccentric shaft 3 is rotatably provided. Figure 2 As shown in , the frame 1 is embedded in the sewing machine and can move up and down, and the eccentric shaft 3 is rotatably connected to the sewing machine. When the eccentric shaft 3 rotates, the frame 1 can move up and down with the eccentric shaft 3, thereby completing the adjustment of the height and tilt angle of the feed dog 11.

[0031] like Figure 1 and Figure 2 As shown, an adjusting disk 4 is fixedly arranged on the eccentric shaft 3, and the adjusting disk 4 is used to be detachably connected with the sewing machine and to abut against the sewing machine. The adjusting disk 4 is arranged at one end of the eccentric shaft 3 away from the frame 1, and a locking piece is also arranged on the adjusting disk 4 for limiting the displacement of the adjusting disk 4. In specific implementation, when making adjustments, it is only necessary to remove the locking piece to rotate the adjusting disk 4, thereby realizing the rotation of the adjusting disk 4 and completing the adjustment of the inclination angle and height of the feed dog 11.

[0032] like Figure 1 and Figure 2 As shown, the adjusting disk 4 is provided with a clearance groove 41, and a locking piece is arranged at the clearance groove 41. The locking piece passes through the clearance groove 41, and the locking piece is used to be detachably connected with the sewing machine and can cooperate with the sewing machine to clamp the adjusting disk 4. In specific implementation, the locking piece includes a locking bolt 42, and the locking bolt 42 is used to be threadedly connected with the sewing machine. The head of the locking bolt 42 is used to press the adjusting disk 4 tightly. The head of the locking bolt 42 can cooperate with the sewing machine to clamp the adjusting disk 4 between the locking bolt 42 and the sewing machine. The locking bolt 42 is provided with an anti-slip pattern 421, and the anti-slip pattern 421 is arranged around the head of the locking bolt 42. In other embodiments, the locking piece can also include a push rod, and a pressing block is arranged on the push rod. Pressing the adjusting disk 4 in a pushing manner can also play a role in limiting the position of the adjusting disk 4. The locking piece can also include a pressing block connected to the sewing machine by a spring, and the spring can pull the pressing block toward the adjusting disk 4, thereby completing the locking. When adjustment is required, the pressing block can be pulled out to push the adjusting disk 4.

[0033] like Figure 1 and Figure 2 As shown, the clearance groove 41 on the adjusting disk 4 is arranged in a fan shape, and the locking member is embedded in the clearance groove 41. In specific implementation, the clearance groove 41 can limit the rotation of the adjusting disk 4 under the cooperation of the locking member, thereby reducing the situation where the adjusting disk 4 rotates excessively.

[0034] like Figure 1 and Figure 2 As shown, the adjusting disk 4 is also provided with a paddle 43, which is integrally provided with the adjusting disk 4, is hook-shaped, and is integrally provided with the adjusting disk 4, and is pushed by a user. In specific implementation, after the locking member is removed, the adjusting disk 4 can be adjusted to rotate by pushing the paddle 43, thereby driving the eccentric shaft 3 to rotate, thereby adjusting the height and tilt angle of the feed dog 11.

[0035] like Figure 1 and Figure 2As shown, a mounting hole 44 is provided on the plectrum 43, and a latch is inserted into the mounting hole 44, and the latch is used to be detachably connected to the sewing machine. In specific implementation, the latch can further fix the plectrum 43 and the sewing machine, thereby further improving the stability after the position is fixed.

[0036] Working principle: When making adjustments, you need to first remove the locking bolt 42, and then rotate the adjusting disk 4 through the paddle 43. At this time, the adjusting disk 4 can drive the eccentric shaft 3 to rotate, thereby driving the frame 1, and the frame 1 can move up and down to complete the angle and height adjustment. After the adjustment is completed, retighten the locking bolt 42.

[0037] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
