[0017] The following are specific embodiments of the present utility model in combination with the drawings, and the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.
[0018] As Figures 1 - 3As shown in the figure, this automatic double-sided sewing machine for blankets includes a machine base 1 and two sewing main bodies 13. A hemming guiding structure 14 for hemming the blankets is installed on the sewing main bodies 13. In this embodiment, the hemming guiding structure 14 adopts an existing structure, which can automatically hem both ends of the blanket fabric. After hemming, the sewing main body 13 can automatically sew the hemmed part, which is realized by existing technology; a first bracket 7 is installed on the machine base 1, a first guide rod 9 is horizontally installed on the first bracket 7, two first guide blocks 5 are slidably connected to the first guide rod 9, a single-direction screw rod 2 is horizontally rotatably installed on the first bracket 7, a first handwheel 8 is provided on the single-direction screw rod 2, a first nut 4 is threadedly connected to the single-direction screw rod 2, the first nut 4 is connected to one of the first guide blocks 5, a second bracket 10 is fixed between the two first guide blocks 5, a second guide rod 19 is horizontally installed on the second bracket 10, two second guide blocks 15 are slidably connected to the second guide rod 19, a double-direction screw rod 18 is horizontally rotatably installed on the second bracket 10, a second handwheel 11 is provided on the double-direction screw rod 18, two second nuts 17 are threadedly connected to the double-direction screw rod 18, one nut is connected to one of the second guide blocks 15, and the other nut is connected to the other second guide block 15. The two sewing main bodies 13 are respectively installed on the two second guide blocks 15 through mounting seats 12; with this structure, by driving the single-direction screw rod 2 to act through the first handwheel 8, the position of the second bracket 10 can be adjusted, and thus the overall position of the two sewing main bodies 13 can be adjusted; by driving the double-direction screw rod 18 to act through the second handwheel 11, the distance between the two sewing main bodies 13 can be synchronously adjusted, so that the two sewing main bodies 13 can approach or move away from each other.
[0019] A locking screw 3 is threadedly connected to the first guide block 5, and a locking screw 16 is threadedly connected to the second guide block 15.
[0020] Both the locking screw 3 and the locking screw 16 are hand-tightening parts.
[0021] A machine shell 20 is also installed on the sewing main body 13. A movable rod 22 is vertically arranged on the machine shell 20. The upper end of the movable rod 22 is connected to a detection wheel 21, the lower end of the movable rod 22 is connected to a blocking piece 24, a spring 25 is also sleeved on the movable rod 22, and a photoelectric switch 23 that cooperates with the blocking piece 24 is also installed on the machine shell 20. The photoelectric switch 23 is electrically connected to the electric control host through a circuit. With this structure, during sewing, the detection wheel 21 abuts against the lower surface of the edge of the sewn blanket. When an abnormality occurs during sewing and causes a downward bulge at the edge, the detection wheel 21 will overcome the elastic force of the spring 25 and move downward, and the blocking piece 24 will be inserted into the sensing part of the photoelectric switch 23 to generate a corresponding signal. The photoelectric switch 23 transmits this signal to the electric control host, and the fact that the photoelectric switch 23 is electrically connected to the electric control host through a circuit is realized by existing technology.
[0022] A self-locking universal wheel 6 is also installed on the machine base 1. With this structure, the whole mechanism can be conveniently moved.
[0023] In the present utility model, the distance between the two sewing main machines 13 can be synchronously adjusted. At the same time, the overall position of the two sewing main machines 13 can also be adjusted, so that it can be conveniently used for the sewing operation of blankets with different widths, and the adjustment is convenient.
[0024] The above components are all common standard components or components known to those skilled in the art. Their structures and principles can all be known by those skilled in the art through technical manuals or through conventional experimental methods.
[0025] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
