Description

Technical Field

[0001] The utility model relates to the technical field of parasol processing equipment, in particular to an automatic device for sewing parasol ribs. Background Art

[0002] A sun umbrella is an umbrella that is mainly used to block direct sunlight. It can block about 70% of ultraviolet rays, but it cannot block reflected ultraviolet rays.

[0003] At present, most of the parasol ribs on the market are sewn by traditional manual sewing, but manual sewing is inefficient, with many defective products, and is not safe for workers' fingers, which can easily prick their fingers. In recent years, sewing machines have gradually been used to sew the ribs and leaves, but during the sewing process, workers need to hold the ribs and leaves by hand, which still consumes manpower and has the risk of being pricked.

[0023] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] See also Figure 1-4 The utility model provides an automatic device for sewing parasol ribs, comprising a workbench 1, and a sewing machine head 2 is fixedly connected to the top of the workbench 1.

[0025] A pay-off rack 3 is arranged on the top of the workbench 1, a wire storage device 301 is arranged at one end inside the pay-off rack 3, a rotary hook 302 is arranged at the other end inside the pay-off rack 3, a cover plate 303 is arranged on the top of the pay-off rack 3, locking bolts 4 are arranged at the four corners of the cover plate 303, the locking bolts 4 penetrate the cover plate 303 and are threadedly connected to the pay-off rack 3, so as to facilitate the opening and closing of the cover plate 303, and a cover plate 303 is also arranged on the top of the wire storage device 301, so as to facilitate the replacement of the rotary hook 302 and the wire storage device 301.

[0026] In this embodiment, the thickness of the cover plate 303 is five millimeters and the cover plate 303 is made of tempered glass, which is convenient for the staff to check the remaining material of the suture thread in the rotary hook 302 and the thread storage device 301.

[0027] An umbrella rib positioning frame 5 is arranged on the side of the workbench 1 away from the suturing machine head 2, and an axle seat 6 is embedded and fixedly connected on the top of the workbench 1. The bottom center of the umbrella rib positioning frame 5 is connected to the bearing of the axle seat 6. At least two umbrella rib positioning frames 5 are arranged on the top of the workbench 1, and the orientation of the umbrella rib positioning frames 5 can be rotated to adjust.

[0028] Both ends of the bottom of the umbrella rib positioning frame 5 are fixedly connected with anti-skid rubber pads 7. When the staff does not manually adjust the direction of the umbrella rib positioning frame 5, the anti-skid rubber pads 7 can be used to position it to prevent it from rotating.

[0029] The top of the rib positioning frame 5 is rotatably connected with a clip 8. The cross section of the rib positioning frame 5 is arranged in an arc shape, and the clip 8 is arranged corresponding to the arc of the top surface of the rib positioning frame 5, so that the ribs and the sun umbrella leaves can be clamped by the rib positioning frame 5 and the clip 8. The clip 8 is connected to the top of the rib positioning frame 5 by a spring hinge, and the elasticity of the spring hinge makes it easy to bring the clip 8 and the rib positioning frame 5 close to each other to clamp the umbrella leaves.

[0030] When in use, the staff can manually adjust the direction of the umbrella rib positioning frame 5 so that it is convenient to place the umbrella ribs and umbrella leaves on the top after it is rotated. The umbrella rib positioning frame 5 is provided with a clip 8 on the outside. Since the umbrella rib positioning frame 5 and the clip 8 are both arranged in an arc shape, it is convenient to fit the arc shape of the umbrella leaves, so that the umbrella ribs and umbrella leaves can be unfolded and placed.

[0031] When the umbrella leaves are clamped by the clamping pieces 8 and the umbrella rib positioning frames 5 , the umbrella ribs are located between the two umbrella rib positioning frames 5 , so as to be easily inserted into the bottom of the sewing machine head 2 , and then the umbrella ribs and the umbrella leaves are sewn by the sewing machine head 2 .

[0032] If the positioning strength of the umbrella leaf needs to be strengthened to keep it stable, the number of the umbrella rib positioning frames 5 can be increased, so that when the umbrella ribs and umbrella leaves are sewn, there is no need for the staff to hold them by hand, which not only saves manpower but also avoids injuries to the staff's fingers.

[0033] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
