[0038] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0039] The utility model provides an industrial sewing machine for school uniform processing, comprising:

[0040] Loading plate 1;

[0041] The lifting plate 2 is arranged above the carrying plate 1;

[0042] The industrial sewing machine body 3 is arranged on the upper end surface of the lifting plate 2;

[0043] The industrial sewing machine body 3 is fixedly mounted on the upper end surface of the lifting plate 2, so that the industrial sewing machine body 3 and the lifting plate 2 can be fixed to each other;

[0044] The housing 4 is fixedly mounted on the upper end surface of the carrier plate 1;

[0045] The housing 4 can be fixed to the carrying plate 1;

[0046] The protective shell 5 is fixedly mounted on the lower end surface of the lifting plate 2 and is slidably connected to the housing 4;

[0047] A driving mechanism is provided in the housing 4 and is used to drive the protective shell 5 to rise and fall;

[0048] Under the action of the driving mechanism, the protective shell 5 can drive the lifting plate 2 and the industrial sewing machine body 3 to rise or fall, and the height of the industrial sewing machine body 3 can be adjusted to facilitate use by workers of different heights.

[0049] Specifically, the driving mechanism includes:

[0050] Two pairs of internally threaded sleeves 6, one end of which is rotatably connected to the lower end surface of the housing 4 and the other end of which passes through the upper wall of the housing 4;

[0051] A drive plate 7 is provided in the protective shell 5;

[0052] The threaded rod 8 is disposed in the internal threaded sleeve 6, and the top end is fixedly connected to the lower end surface of the driving plate 7;

[0053] A rotating shaft 9 is rotatably mounted on the inner lower end surface of the housing 4;

[0054] The first gear 10 has a lower end surface fixedly connected to the top of the rotating shaft 9;

[0055] The second gear 11 is fixedly mounted on the outer surface of the internally threaded sleeve 6 and is meshed with the first gear 10;

[0056] The rotation of the first gear 10 can drive the rotation of the second gear 11, and the rotation of the second gear 11 can drive the internal threaded sleeve 6 to rotate at the same time, which can be threadedly connected to drive the threaded rod 8 to move. At this time, the movement of the threaded rod 8 can drive the driving plate 7 to move. At this time, the upper end surface of the driving plate 7 contacts the inner upper end surface of the protective shell 5, supporting the protective shell 5 and driving the protective shell 5, the lifting plate 2 and the industrial sewing machine body 3 to rise;

[0057] The damping mechanism is provided in the housing 4 and is used to provide damping for the protective shell 5 .

[0058] Specifically, the driving mechanism also includes:

[0059] The carrier 12 is fixedly mounted on the inner upper end surface of the housing 4;

[0060] The reducer 13 is fixedly mounted on one end surface of the carrier 12, and the output end is fixedly connected to the upper end surface of the first gear 10;

[0061] The three-phase motor 14 is fixedly mounted on one end surface of the carrier 12, and the output end is fixedly connected to the input end of the reducer 13;

[0062] The rotation of the output end of the three-phase motor 14 can drive the output end of the reducer 13 to rotate. At this time, the reducer 13 can reduce the speed of the output of the three-phase motor 14 and drive the first gear 10 to rotate. At the same time, the output end of the three-phase motor 14 can rotate forward or reverse, which can drive the first gear 10 to rotate forward or reverse, and can drive the drive plate 7 to rise or fall.

[0063] Specifically, the damping mechanism includes;

[0064] There are two pairs of fixed shells 15, both fixedly mounted on the inner lower end surface of the housing 4 and filled with oil;

[0065] Two pairs of openings 16 are formed in the upper wall of the housing 4 and are located above the two pairs of fixed shells 15 respectively;

[0066] A slide rod 17, one end of which slides through the upper wall of the fixed shell 15, and the other end of which passes through the opening 16 and is fixedly connected to the upper end surface of the interior of the protective shell 5;

[0067] The sliding plate 18 is disposed in the fixed housing 15 and is fixedly connected to the bottom end of the sliding rod 17;

[0068] a through hole 19 formed in the sliding plate 18;

[0069] A compression spring 20 is wound around the outer surface of the slide bar 17;

[0070] The two ends of the compression spring 20 are fixedly connected to the upper end surface of the fixed shell 15 and the upper end surface inside the protective shell 5 respectively, which can apply an upward force to the protective shell 5. At this time, the output end of the three-phase motor 14 is reversed to make the drive plate 7 descend and move away from the protective shell 5. At this time, the lifting plate 2 and the industrial sewing machine body 3 drive the slide bar 17 to slide in the fixed shell 15 under the action of gravity. At the same time, when the slide bar 17 slides, it can drive the sliding plate 18 to slide in the fixed shell 15, so that the oil in the fixed shell 15 flows from the through hole 19 to the top of the sliding plate 18, which can play a damping role, so that the lifting plate 2 can slowly descend. At the same time, the descent of the lifting plate 2 can compress the compression spring 20, so that the compression spring 20 can play a damping role on the lifting plate 2.

[0071] Specifically, a limiting groove 21 is formed in the outer wall of the shell 4, and a limiting block 22 is fixedly installed on the inner wall of the protective shell 5 and is slidably connected to the limiting groove 21;

[0072] Under the action of the limiting block 22 and the limiting groove 21 , the protective shell 5 can remain stable when sliding.

[0073] Specifically, two pairs of universal wheels 23 are rotatably mounted on the lower end surface of the carrying plate 1;

[0074] The universal wheels 23 can facilitate the staff to move the carrying plate 1 and facilitate transportation and movement.

[0075] Working principle: When the industrial sewing machine body 3 is actually used, the height of the industrial sewing machine body 3 needs to be adjusted according to the height of the staff to achieve the most comfortable working height for the staff. When adjusting, the staff starts the three-phase motor 14. The rotation of the output end of the three-phase motor 14 can drive the output end of the reducer 13 to rotate. At this time, the reducer 13 can reduce the speed output by the three-phase motor 14 and drive the first gear 10 to rotate. The rotation of the first gear 10 can drive the second gear 11 to rotate. The rotation of the second gear 11 can drive the internal threaded sleeve 6 to rotate at the same time. It can be threadedly connected to drive the threaded rod 8 to move, so that the threaded rod 8 moves out of the internal threaded sleeve 6. At this time, the movement of the threaded rod 8 can drive the drive plate 7 moves upward, at this time the upper end surface of the driving plate 7 contacts the inner upper end surface of the protective shell 5, carries the protective shell 5, and drives the protective shell 5, the lifting plate 2 and the industrial sewing machine body 3 to rise. Conversely, the output end of the three-phase motor 14 is reversed, which can make the driving plate 7 fall. At this time, the lifting plate 2 and the industrial sewing machine body 3 drive the slide bar 17 to slide in the fixed shell 15 under the action of gravity, so that the compression spring 20 is compressed. At the same time, when the slide bar 17 slides, it can drive the sliding plate 18 to slide in the fixed shell 15, so that the oil in the fixed shell 15 flows from the through hole 19 to the top of the sliding plate 18, which can play a damping role, so that the lifting plate 2 can slowly descend, and the height of the industrial sewing machine body 3 can be adjusted, which brings convenience to people.
