Description

Technical Field

[0001] The utility model relates to the technical field of knitting, and particularly relates to a novel template sewing machine. Background Art

[0002] A template sewing machine refers to a machine that combines garment template CAD software, garment template sewing CAD software, and advanced numerical control technology for fully automatic template production, improving production efficiency and product quality, reducing the technical requirements for technical workers, and replacing the original manually operated sewing machine with a computer-controlled machine with a higher degree of automation. For example, Chinese Patent Application No. CN202220196690.2 discloses a template sewing machine frame, including a frame body. A base foot for fixing the frame and rollers for moving are provided on the lower side of the frame body. A base is provided in the middle of the frame body. Guide rail seats are provided on both sides of the frame body. Guides are installed on the guide rail seats. A walking bracket straddles between the guides. The base is hollow. A fixed support plate is provided on the base. A bobbin base is installed at the front end of the base. A head cantilever is installed on the fixed support plate. However, the overall base on the existing template sewing machine frame includes a base, a head cantilever, and a head, making the overall weight of the base too large. When the ground is uneven, due to the large overall weight of the base, the base presses down on the frame as a whole, and due to the uneven ground, the force is uneven, resulting in deformation of the frame body due to the uneven force caused by the overall downward pressure of the base. The deformation of the frame body causes the overall base to shift, and then the head on the overall base cannot maintain the vertical accuracy with the horizontal plane during processing, and further affects the sewing quality of the fabric when the head performs knitting. Content of the Utility Model

[0003] Therefore, in view of the above problems, the utility model proposes a novel template sewing machine that can avoid the deformation of the frame due to uneven ground, affecting the vertical accuracy of the head processing and improving the sewing quality.

[0004] To solve this technical problem, the utility model adopts the following scheme: A novel template sewing machine, including a frame body, a base, and a head cantilever provided on the base. The rear part of the base is fixedly connected to the rear part of the frame body. A connecting piece is fixedly provided on the lower side of the front part of the base, and the connecting piece extends downward to form a connecting part. A circular mounting hole is provided on the connecting part of the connecting piece. A support rod is provided at the front part of the frame body, and a support block that can penetrate into the circular mounting hole of the connecting part is provided on one side below the front part of the base of the support rod of the frame body. The upper surface of the support block is provided with an arc surface adapted to the inner wall of the circular mounting hole, and the width of the middle part of the support block is smaller than the diameter of the circular mounting hole. The support block of the support rod of the frame body is inserted into the circular mounting hole of the connecting part on the connecting piece to support the front part of the base.

[0005] Further improvement: The connecting piece includes a fixing plate and a connecting portion. The connecting portion is fixedly arranged on the bottom surface of the fixing plate, and the top surface of the fixing plate is fixedly connected to the base. There is a gap between the bottom surface of the fixing plate and the support rod.

[0006] Further improvement: The lower surface of the support block is a second arc surface adapted to the inner wall of the circular mounting hole.

[0007] Even further improvement: Both sides of the middle part of the support block are flat surfaces.

[0008] By adopting the foregoing technical solutions, the beneficial effects of the present utility model are as follows: By arranging a connecting piece at the front part of the base, a circular mounting hole is arranged on the connecting portion of the connecting piece, and a support rod is arranged at the front part of the frame body. A support block that can penetrate into the circular mounting hole of the connecting portion is arranged on one side below the front part of the base, so that the support block of the support rod of the frame body is inserted into the circular mounting hole of the connecting portion on the connecting piece to support the front part of the base. When the overall component composed of the base, the head cantilever and the head is overweight and pressed down due to the uneven ground, the force will be uneven and cause the frame to deform. However, since the front part of the base is sleeved on the support block by the circular mounting hole between the connecting portion of the connecting piece and the support rod of the frame body, when the frame body deforms and the support block shifts, the base will produce self-adaptive adjustment and correction due to the cooperation between the circular mounting hole and the upper arc surface of the support block. Thus, when the support block shifts due to uneven force and deformation of the frame body, the base always maintains the vertical accuracy with the horizontal plane due to the self-adaptive adjustment and correction of the circular mounting hole, that is, the circular mounting hole changes the vertical inclination shift generated by the support block into the vertical up-and-down shift, so that the base and the head cantilever on the base and the head mounted on the head cantilever maintain the vertical accuracy with the horizontal plane, realizing the problem of avoiding the influence of frame deformation caused by uneven ground on the vertical accuracy of head processing, improving the sewing quality of the head. Further setting, that is, there is a gap between the bottom surface of the fixing plate and the support rod, which makes a gap between the base and the frame body, facilitating the self-adaptive correction of the circular mounting hole on the connecting portion of the connecting piece. The lower surface of the support block is a second arc surface adapted to the inner wall of the circular mounting hole, making the self-adaptive adjustment and correction structure between the circular mounting hole and the support block smoother, and it can be widely promoted and applied.

The connecting member 4 includes a fixing plate 41 and a connecting portion 42. The connecting portion 42 is fixedly provided on the bottom surface of the fixing plate 41, and the top surface of the fixing plate 41 is fixedly connected to the base 2. The connecting portion 42 is perpendicular to the fixing plate 41. A circular mounting hole 421 is provided on the connecting portion 42 of the connecting member 4. A support rod 11 is provided at the front part of the frame body 1, and a support block 5 that can penetrate into the circular mounting hole 421 of the connecting portion 42 is provided on one side below the front part of the base 2 of the support rod 11. An arc surface 51 adapted to the inner wall of the circular mounting hole 421 is provided on the upper surface of the support block 5, and the width of the middle part of the support block 5 is smaller than the diameter of the circular mounting hole 421. Both sides of the middle part of the support block 5 are flat surfaces 52. The lower surface of the support block 5 is a second arc surface 53 adapted to the inner wall of the circular mounting hole 421.
