Description

Technical Field

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

[0002] Currently, sewing machines are generally equipped with a pressing mechanism to press the fabric firmly, thereby saving time and improving work efficiency. However, most existing pressing plates use a parallel pressing method. If the sewing fabric is of uneven thickness or the table surface is uneven, problems such as fabric slippage and snagging can easily occur, hindering automated operation. This can also cause the fabric to shift when pushed into the pressing plate, resulting in many inconveniences and affecting work efficiency.

[0003] Chinese patent application 202021037598.9 discloses a pressing structure and a pattern template sewing machine, including a slider seat, a material support plate, and a pressing assembly. The pressing assembly is mounted above the material support plate and can clamp or release relative to the material support plate. The pressing assembly includes an L-shaped pressing frame, pressing frame ears, and a pressing plate. The pressing plate has an angled structure and has several weight-reducing grooves. The L-shaped pressing frame is provided with a tripod and a reinforcing plate. The tripod and the reinforcing plate are respectively fastened to two sides of the L-shaped pressing frame, and the other side of the tripod is fastened to the reinforcing plate.

[0004] The above-mentioned technical solution has the following drawbacks: large overall machine size, large space occupation, fixed pressure plate, poor flexibility, low pressure efficiency, low pressure stability, and poor practicality. Utility Model Content

The upper and lower cantilever are parallel to each other and fixedly connected to the frame. The platform is horizontally arranged between the upper and lower cantilever, with one end fixedly connected to the frame and the other end fixedly connected to the lower cantilever. Parallel X-axis tracks are provided on both the upper and lower cantilever. The upper and lower sewing heads are respectively equipped with... The upper and lower cantilever rails are at the same position and can move along the X-axis. A Y-axis rail is provided below the upper cantilever. The slider seat is located on the Y-axis rail and can move along the Y-axis. The material support plate is fixedly connected to the slider seat and simultaneously contacts the platform in parallel. The pressure bracket is connected to the slider seat through a clutch device. The pressure plate is connected to the pressure bracket and can move up and down relative to the slider seat under the action of the clutch device, contacting or separating from the material support plate. The rotary shuttle is located inside the lower head. A drive shaft is vertically installed inside the frame. The drive shaft is connected to the upper head and lower head respectively through an upper belt and a lower belt. The motor is connected to the drive shaft.

[0006] Furthermore, the clutch device consists of a cylinder and a guide rail.

[0007] Furthermore, there are two sets of the cylinder and guide rail, the pressure bracket and the pressure plate.

[0008] Furthermore, the pressure plate is L-shaped.

[0009] The beneficial effects of this utility model are as follows:

[0010] This utility model discloses a cylindrical automatic sewing machine. By having the upper and lower sewing heads move synchronously on the upper and lower cantilever arms respectively, it achieves the pressing and leveling functions of the pressure plate and large-sized sewing fabric. It has the advantages of compact structure, small space occupation, convenient processing, and low cost. It also makes the mechanism more stable in operation, easy to install and adjust, and can be used for various large-sized sewing products, especially suitable for cylindrical sewing products, which greatly improves the working efficiency of the whole machine.

Detailed Implementation

[0014] To facilitate understanding and implementation of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figure 1 , Figure 2As shown, this utility model provides a cylindrical automatic sewing machine, including a frame 1, a table 2, an upper cantilever 3, a lower cantilever 4, an upper sewing head 5, a lower sewing head 6, a slider seat 7, a pressure plate 8, a pressure plate 9, a material support plate 10, and a rotary hook 11. The upper cantilever 3 and the lower cantilever 4 are fixedly connected to the frame 1 in parallel. The table 2 is horizontally arranged between the upper cantilever 3 and the lower cantilever 4, with one end fixedly connected to the frame 1 and the other end fixedly connected to the lower cantilever 4. Both the upper cantilever 3 and the lower cantilever 4 are provided with parallel X-axis tracks. The upper sewing head 5 and the lower sewing head 6 are respectively arranged on the upper cantilever 1, lower sewing head 6, and lower sewing head 11. At the same position on the tracks of cantilever 3 and lower cantilever 4, both can move along the X-axis, a drive shaft 12 is vertically installed inside the frame 1. Driven by motor 15, the drive shaft 12 simultaneously drives the upper machine head 5 and lower machine head 6 to move synchronously on the X-axis tracks of the upper cantilever 3 and lower cantilever 4 via parallel upper belt 13 and lower belt 14. A Y-axis track is provided below the upper cantilever 3, and the slider seat 7 is set on the Y-axis track and can move along the Y-axis. The material support plate 10 is fixedly connected to the slider seat 7 and is in parallel contact with the platform 2, and can... As the slider seat 7 moves along the Y-axis, two sets of cylinders 16 and guide rails 17 are vertically arranged on the slider seat 7. Each set of guide rails 17 is equipped with a pressure bracket 8, which can move up and down along the guide rail 17. The movable end of the cylinder 16 is fixedly connected to the pressure bracket 8. The L-shaped pressure plate 9 is fixedly connected to the pressure bracket 8 through screw holes, and its relative position to the pressure bracket 8 can be adjusted by selecting the corresponding screw holes. When the cylinder 16 pushes downward, the L-shaped pressure plate 9 moves downward along the guide rail 17 with the pressure bracket 8, and the L-shaped pressure plate 9 contacts the support plate 10. When the cylinder 16 is lifted upward, the L-shaped pressure plate 9 separates from the support plate 10. The two sets of pressure brackets 8 and the L-shaped pressure plate 9 can move up and down simultaneously or individually under the control of their respective cylinders 16 and guide rails 17. The sewing mechanism in the upper head 5 can move along the X-axis while sewing the fabric pressed by the L-shaped pressure plate 9 and the support plate 10 under the drive of the motor inside the upper head 5. The rotary shuttle 11 is set in the lower head 6. The rotary shuttle 11 supplies thread to the sewing mechanism in the upper head 5 through the motor inside the lower head 6.
