Detailed Description
As mentioned in the background section, current sewing machines are less suitable for fabrics of different thicknesses.
Based on the research, the embodiment of the invention provides a thick material sewing machine, and the feeding eccentric wheel and the feed lifting eccentric wheel are two independent parts, so that the feeding eccentric wheel and the feed lifting eccentric wheel can be independently adjusted, namely the mounting angles of the feeding eccentric wheel and the feed lifting eccentric wheel and the main shaft are respectively rotated, and the thick material sewing machine has better applicability and meets the requirements of sewing fabrics with different thicknesses.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
In the following description, specific details are set forth in order to provide a thorough understanding of the present invention. The invention can be implemented in a number of ways different from those described herein and similar generalizations can be made by those skilled in the art without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
Referring to fig. 1 to fig. 3, fig. 1 is a schematic perspective view of a thick material sewing machine according to an embodiment of the present invention; FIG. 2 is a schematic diagram of a side view of a thick material sewing machine according to an embodiment of the present invention; fig. 3 is a schematic structural view of a presser foot plate of a thick material sewing machine according to an embodiment of the present invention.
One embodiment of the present invention provides a thick material sewing machine, including: the thread take-up component comprises a main shaft 2, a feeding connecting rod 5, a tooth lifting connecting rod 6, a foot pressing plate 10 and a thread take-up rod component 1 with a preset length, wherein the thread take-up rod component 1 is hinged to the main shaft 2 through a needle rod crank, an elevation angle and a depression angle of a preset angle are arranged on the foot pressing plate 10, a feeding eccentric wheel 4 and a tooth lifting eccentric wheel 3 are arranged on the main shaft 2, the feeding eccentric wheel 4 and the tooth lifting eccentric wheel 3 are mutually independent, the upper portion of the feeding connecting rod 5 is sleeved on the feeding eccentric wheel 4, and the upper portion of the tooth lifting connecting rod.
In this embodiment, the inclination of the elevation angle and the depression angle of the presser foot plate 10 can be increased properly relative to the conventional presser foot plate, and the take-up lever assembly 1 can also be increased properly, so that the take-up amount can be increased when a thick fabric is sewn, and the presser foot plate 10 with an increased angle can be matched to easily pass through the ridge, and in addition, the feeding eccentric wheel 4 and the tooth lifting eccentric wheel 3 are two mutually independent parts, so that the adjustment can be carried out independently, namely, the mounting angles of the feeding eccentric wheel 4 and the tooth lifting eccentric wheel 3 and the main shaft 2 are respectively rotated, so that the applicability is good, and the sewing of fabrics with different thicknesses can be met.
Further, the elevation angle and the depression angle of the preset angle of the foot pressing plate are respectively +18 degrees in elevation angle and-18 degrees in depression angle. Compared with the traditional footpad with the elevation angle of +10 degrees and the depression angle of-15 degrees, the footpad 10 provided by the embodiment can easily climb over when the footpad 10 reaches the seam thickness and passes the threshold. It should be noted that the elevation angle and the depression angle are only preferred angle values, and may be modified appropriately according to actual situations, which is not limited in this embodiment.
Wherein, the bottom of the feeding connecting rod 5 is hinged with the feeding shaft 8 through a feeding crank. The feed lifting connecting rod 6 is hinged with the feed lifting shaft 7 through a feed lifting crank. The device also comprises a tooth rack assembly 9, wherein one end of the tooth rack assembly 9 is fixedly connected with the tooth lifting shaft 7, and the other end of the tooth rack assembly 9 is fixedly connected with the feeding shaft 8. The motor drives the main shaft 2 to rotate, so that the feed lifting eccentric wheel 3 and the feed eccentric wheel 4 on the main shaft 2 are driven to move together, the feed lifting shaft 7 and the feed shaft 8 are driven to swing, the tooth rack assembly 9 moves up and down and back and forth, and complete feed movement is achieved.
