Description

Technical Field

[0001] The utility model relates to the field of carpet processing, and more particularly to a device for sewing the edge of a double-layer thickened carpet. Background Art

[0002] A fleece blanket is a cotton pile blanket. It can be categorized into cotton blankets and waste cotton blankets based on the quality of the cotton used. These blankets are thick, soft to the touch, and offer excellent warmth retention.

[0003] China Patent Authorization Announcement No.: CN205152542U, provides a carpet edge sewing device, this patent provides a carpet edge sewing device including an operating table, a cloth winding shaft, scissors, and a sewing machine. The operating table is a rectangular operating table with legs, and the operating table is provided with a groove, and a carpet support is provided in the groove. The upper surface of the carpet support is flush with the upper surface of the operating table, and an electric control device is also provided inside the groove. The operating table is provided with scissors and a slide, and the scissors can move horizontally counterclockwise along the slide. The operating table is also provided with a sewing machine, and the head of the sewing machine is provided with a sewing needle, and a cloth pushing device is provided next to the sewing needle. The sewing machine can move horizontally counterclockwise along the edge of the operating table, and a cooperating sewing device of the sewing machine is also provided in the groove of the operating table. Cloth winding shafts are provided on all sides below the operating table surface.

[0004] In the above patent, although the existing technology can perform hemming on the carpet, the length of the hem is relatively fixed during the hemming process. When adjusting the hem length of the carpet, the overall width of the carpet will also change due to the change in the hem length of the carpet. Since the carpet cannot be supported according to the change in the overall width of the carpet, the carpet body cannot be effectively supported when the hem length is adjusted, making the carpet as a whole not flat. In addition, the hem part of the carpet lacks a pressing mechanism, which causes the hem part of the carpet to gradually warp up due to the toughness of the carpet itself after sewing, which is inconvenient and has limitations when used.

For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0032] Example 1:

[0033] See also Figure 1-5 A double-layer thickened blanket sewing device includes a base 1, a connecting rod 13 is fixedly connected to the top of the base 1, a top plate 14 is fixedly connected to the top of the connecting rod 13, an electric cylinder 11 is fixedly connected to the top of the base 1, the output end of the electric cylinder 11 is fixedly connected to the operating panel 12, a rotating plate 2 is rotatably connected to the bottom of the top plate 14, the end of the rotating plate 2 is rotatably connected to the support frame 21, the outside of the support frame 21 is slidably connected to the mounting plate 15, the mounting plate 15 and the top plate 14 are slidably connected, and an adjusting rod 22 is rotatably connected to the bottom of the top plate 14, and the adjusting rod 22 and the rotating plate 2 are connected by a bevel gear transmission.

[0034] In this embodiment, when the staff rotates the adjusting rod 22, the transmission between the bevel gears will drive the rotating plate 2 to rotate. At this time, the distance between the support frames 21 on both sides of the rotating plate 2 will change. In addition, the staff can also pull the mounting plate 15 to cause relative sliding between the mounting plate 15 and the top plate 14. At this time, the mounting plate 15 will slide on the outer wall of the support frame 21, thereby changing the distance from the mounting plate 15 to the end of the support frame 21, that is: by changing the distance between the two support frames 21, the edges of carpets of different widths can be trimmed, and by changing the distance between the mounting plate 15 and the end of the support frame 21, the width of the carpet seam can be changed.

[0035] Example 2:

[0036] See also Figure 1-5A double-layer thickened blanket sewing device, a sliding rod 23 is slidably connected to the top of the mounting plate 15, and a stopper 24 is fixedly connected to the outer wall of the sliding rod 23. One stopper 24 is located outside the mounting plate 15, and the other stopper 24 is located inside the mounting plate 15. A spring 25 is sleeved on the outside of the sliding rod 23, and the spring 25 is located inside the mounting plate 15. A slide bar 26 is fixedly connected to the top of the top plate 14. The slide bar 26 is slidably connected to the inside of the mounting plate 15, and the top of the slide bar 26 is opened. A limiting groove 27 is provided, and the bottom end of the sliding rod 23 is clamped in the inside of the limiting groove 27. The inside of the mounting plate 15 is rotatably connected to the screw 16, and the outer wall of the screw 16 is threadedly connected to the moving block 17. The moving block 17 is slidably connected to the inside of the mounting plate 15, and the bottom of the moving block 17 is rotatably connected to the support rod 18. The end of the support rod 18 away from the moving block 17 is rotatably connected to the pressure plate 19. A slide rail 28 is fixedly connected to one side of the top plate 14, and a sewing head 29 is slidably connected to the outer wall of the slide rail 28.

[0037] In this embodiment, the staff can pull the sliding rod 23 upward to disengage the bottom end of the sliding rod 23 from the inside of the limit groove 27 opened by the slide bar 26, thereby releasing the limit between the mounting plate 15 and the slide bar 26. During this process, the spring 25 will be squeezed and elastically deformed and contracted, and then the mounting plate 15 can be slid. After the mounting plate 15 slides to the desired position, the sliding rod 23 is released, and the spring 25 in the elastic contraction state will rebound, thereby driving the sliding rod 23 to reset, so that the lower end of the sliding rod 23 is re-engaged in the inside of the limit groove 27 directly below it. In addition, the staff can rotate the screw 16 to make the moving blocks 17 at both ends of the screw 16 approach each other. At this time, the support rod 18 will deflect at a certain angle, thereby driving the pressure plate 19 to descend, so as to complete the compaction of the part of the carpet that is about to be sealed.

[0038] The working principle of the present invention is as follows: if the carpet needs to be sewn, the staff can place the carpet above the operating plate 12, and then adjust the distance between the mounting plate 15 and one end of the support frame 21, and then bend the two sides of the carpet along the end of the support frame 21, and bend its end into the interior of the mounting plate 15, and then rotate the screw 16 to drive the pressing plate 19 to press down to complete the compaction of the part of the carpet to be sewn, and then the staff will pull the bent and compacted carpet along the direction of the sewing head 29, and finally the sewing head 29 will sew the bent part.

[0039] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
