[0002] In the production of pillows, sealing sewing is the last step and also a very critical step. At present, in pillow production factories, pillows are generally sealed by workers operating sewing machines, which requires the sealing employees to be proficient in operation, otherwise the suture line will bend, affecting the yield rate of the pillow. In addition, in order to improve the aesthetics and sealing firmness of the pillow, the overlocking process is also added when the pillow is sealed to improve the quality of the pillow. When the existing overlocking machine is sealing and overlocking, the side of the pillow to be sealed may be raised, which increases the difficulty of operation for workers. If they are not careful, the edge will bend, affecting the quality of the pillow. Summary of the invention

[0010] Preferably, the guide member is fixedly connected to the lifting frame via a connecting plate, and the fixing hole on the connecting plate is a strip-shaped hole.

[0011] The beneficial effects of the present invention are as follows: a sewing mechanism of an overlocking machine of the present invention comprises a frame, a workbench arranged on the frame and a sewing device arranged on the frame and the workbench, a fixed frame is arranged on the side wall of the sewing device, a telescopic cylinder is longitudinally arranged on the fixed frame, a lifting frame is fixedly arranged at the telescopic end of the telescopic cylinder, a guide is arranged on the front side of the lifting frame, the guide member comprises a vertically arranged front guide plate and an inclined top guide plate; the inclined top guide plate can gradually flatten the raised part of the side edge of the pillow to be sealed during the process of the pillow to be sealed moving toward the sewing device, without the need for workers to adjust it manually, and at the same time, the lateral guide plate can make the side edge of the pillow flattened by the top guide plate continue to maintain a flat state until it moves to a position near the needle of the sewing device, providing protection for subsequent sealing and overlocking. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural schematic diagram of the present invention;

[0013] Figure 2 It is a structural schematic diagram of another viewing angle of the present invention. DETAILED DESCRIPTION

[0014] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation methods.

[0015] like Figure 1-Figure 2The sewing mechanism of the overlocking machine shown in the figure comprises a frame 1, a workbench 2 arranged on the frame 1, and a sewing device 4 arranged on the frame 1 and the workbench 2, wherein the sewing device 4 is an existing sewing overlocking device with trimming and thread cutting. A mounting notch 22 matching with the sewing device 4 is provided on the side of the workbench 2 close to the sewing device 4, and the front side of the sewing device 4 is embedded in the mounting notch 22 and connected with the workbench 2. A fixing frame 3 is provided on the side wall of the sewing device 4, and a telescopic cylinder 8 is longitudinally arranged on the fixing frame 3, and a lifting frame 5 is fixedly arranged at the telescopic end of the telescopic cylinder 8, and a guide member 6 is provided on the front side of the lifting frame 5, and the guide member 6 comprises a vertically arranged front guide plate 61 and an inclinedly arranged top guide plate 62, and the side of the top guide plate 62 close to the sewing device 4 is a low side, and the side of the top guide plate 62 away from the sewing device 4 is a high side, and there is a gap between the lower edge of the front guide plate 61 and the table surface of the workbench 2 for the sewing object to pass through. The telescopic cylinder 8 can be an electric telescopic cylinder or a pneumatic cylinder. The inclined top guide plate 62 can gradually flatten the raised part of the side edge of the pillow to be sealed when the pillow to be sealed moves toward the sewing device 4, without the need for workers to adjust it manually, thus providing guarantee for the subsequent sealing and flanging.

[0016] As a preferred solution, a transverse guide plate 63 is further provided on the side of the top guide plate 62 close to the sewing device 4. The transverse guide plate 63 can keep the side of the pillow flat after being flattened by the top guide plate 62 until it moves to a position near the needle of the sewing device 4. In addition, the telescopic cylinder 8 can adjust the overall installation height of the guide member 6 and the size of the gap between the lower edge of the front guide plate 61 and the table top of the workbench 2, so that the guide member 6 can be suitable for pillows of different specifications or other types of sewing objects.

[0017] The guide member 6 is preferably arranged at the lower end of the front side of the lifting frame 5. The guide member 6 is fixedly connected to the lifting frame 5 through a connecting plate 64, and the fixing holes on the connecting plate 64 are strip-shaped holes, which facilitate the installation of the guide member 6 and adjust the installation position.

[0018] As another preferred solution, a waste opening 21 is provided on the workbench 2 at the rear side of the guide member 6, and a waste collection box 7 is provided on the frame 1 below the waste opening 21. The waste cut by the sewing device 4 can fall into the waste collection box 7 below through the waste opening 21 and be collected. The waste collection box 7 can also be connected to a fan to generate negative pressure in the waste collection box 7 to improve the waste collection effect and efficiency.
