Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Embodiment 1: Figure 1-6As shown, the dust filter bag high-efficiency sewing device based on grain screening processing proposed by the present invention comprises a workbench 1, a sewing machine body 2 and a sewing machine head 3, the sewing machine body 2 is arranged near one side of the upper outer surface of the workbench 1, and the sewing machine head 3 is arranged at one end of the sewing machine body 2, and the sewing table 4 is arranged directly below the sewing machine head 3, and the sewing table 4 is fixedly connected to the sewing machine body 2;

[0027] The upper outer surface of the workbench 1 is provided with a support assembly 5 at a position on the right side of the sewing machine head 3. The support assembly 5 includes a mounting plate 51, a motor 52, a rotating plate 53, a support bar 54, an electric telescopic rod 55, a fixed plate 56 and a movable plate 57. The upper outer surface of the workbench 1 is provided with a mounting plate 51 at a position close to the left side of the sewing machine head 3.

[0028] A mounting groove 6 is provided on the outer surface of the upper end of the workbench 1 at a position corresponding to the mounting plate 51, and a slide plate 7 is slidably connected inside the mounting groove 6. An electric telescopic rod 8 is provided at one end of the inner surface of the mounting groove 6, and one end of the electric telescopic rod 8 is fixedly connected to the mounting groove 6, and the other end is fixedly connected to the slide plate 7, and the slide plate 7 is fixedly connected to the mounting plate 51;

[0029] During the process of fitting the filter bag, the slide plate 7 is located inside the mounting groove 6 at one end away from the sewing machine head 3, and a motor 52 is provided on the left outer surface of the mounting plate 51 near the middle. The output shaft of the motor 52 passes through the mounting plate 51 and is fixedly connected to a rotating plate 53. The output shaft of the motor 52 is rotatably connected to the mounting plate 51, and the output shaft of the motor 52 drives the rotating plate 53 to rotate one circle at the same frequency as the sewing machine body 2.

[0030] An electric telescopic rod 55 is fixedly connected to a position near the middle of the side of the outer surface of the rotating plate 53 away from the mounting plate 51, and an end of the electric telescopic rod 55 away from the rotating plate 53 is fixedly connected to a fixed plate 56, and six groups of movable plates 57 are hingedly connected to the outer surface of the fixed plate 56 in a circular shape with equal distances. The end of each group of movable plates 57 of the electric telescopic rod away from the fixed plate 56 is hingedly connected to a support bar 54, and the electric telescopic rod 55 pushes the fixed plate 56 to move;

[0031] During this process, both ends of the movable plate 57 rotate and push the support bar 54 to move along the surface of the rotating plate 53, and one end of the support bar 54 is tightly fitted with the outer surface of the rotating plate 53, reducing the probability of the support bar 54 rotating around the connection with the movable plate 57;

[0032] A slide groove 58 is provided at the connection between the outer surface of one side of the rotating plate 53 and the plurality of groups of support bars 54, and a slider 59 is slidably connected to the inner surface of the slide groove 58. The cross section of the slider 59 is T-shaped and matches the slide groove 58. The slider 59 corresponds to the support bar 54 one by one and is fixedly connected. The support bar 54 drives the slider 59 to move along the slide groove 58 under the action of the movable plate 57, so as to prevent the support bar 54 from rotating around the connection with the movable plate 57 due to uneven force on one end, thereby improving the stability of the support bar 54.

[0033] Before sewing, one end of the filter bag is sleeved on the surface of several groups of support strips 54, and the part to be sewn is facing the sewing machine head 3, and then the electric telescopic rod 55 is started to push the fixed plate 56 to move away from the rotating plate 53. Since the movable plate 57 is hinged to the fixed plate 56, during the movement of the fixed plate 56, both ends of the movable plate 57 rotate and push the support strips 54 to drive the slider 59 to move along the slide groove 58 away from the fixed plate 56 until the filter bag is propped up and the part to be sewn does not contact the support strips 54.

[0034] Then, the bag bottom is sleeved on the sewing table 4, and the electric telescopic rod 28 is started to pull the slide plate 7 to pull the mounting plate 51 towards the sewing machine head 3 until the part to be sewn can be placed on the surface of the sewing table 4 and is directly below the needle of the sewing machine head 3, and the bottom edge of the bag is aligned with the part to be sewn of the filter bag, and then the motor 52 and the sewing machine body 2 are started at the same time, and the sewing machine body 2 sews and traverses the sewing part, and at the same time, the output shaft of the motor 52 drives the rotating plate 53, the support bar 54, the filter bag on its surface, and the bag bottom and the sewing machine body 2 to rotate one circle at the same frequency.

[0035] Embodiment 2: Figure 2-6 As shown, the difference between this embodiment and the first embodiment is that two groups of support blocks 541 are fixedly connected to one end of the outer surface of the support bar 54 away from the movable plate 57 and close to the rotating plate 53, and the two groups of support blocks 541 are fixedly connected to one side corresponding to the two groups of support blocks 541, and a clamping plate 543 is rotatably connected between the two groups of corresponding fixed shafts 542, and a torsion spring 544 is sleeved on the outer surface of the fixed shaft 542, and one end of the torsion spring 544 is fixedly connected to the support block 541, and the other end is fixedly connected to the clamping plate 543;

[0036] The clamping plate 543 is subjected to external force, rotates around the fixed shaft 542 and twists the torsion spring 544, and the clamping plate 543 is always fitted in the direction of the support bar 54 under the elastic force of the torsion spring 544, and a plurality of rolling grooves 545 are equidistantly provided on the outer surface of the clamping plate 543 close to the support bar 54, and the inner part of the rolling groove 545 is fixedly connected with a limit rod 546, and the outer surface of the limit rod 546 is sleeved with a ball 547, and the ball 547 is rollingly connected to the limit rod 546, and the outer surface of the ball 547 is tightly fitted with the outer surface of the support bar 54;

[0037] When the filter bag is sleeved on the surface of the support bar 54, one end of the filter bag is placed between the clamping plate 543 and the support bar 54 and pulled toward the rotating plate 53. During this process, the filter bag drives the ball 547 to rotate around the limit rod 546, and the support bar 54 is acted upon by the torsion spring 544 so that the ball 547 is always in contact with the filter bag.

[0038] The side where the outer surface of the support bar 54 and the outer surface of the ball 547 contact each other is provided with an antistatic layer 548, and the antistatic layer 548 is made of antistatic silicone. The outer surface of the antistatic layer 548 corresponding to the outer surface of the support bar 54 is arc-shaped, and several groups of support bars 54 are arranged in a ring at equal distances. The antistatic layer 548 made of antistatic silicone can prevent the filter bag from generating static electricity with the ball 547 and the support bar 54 during the sleeve connection process;

[0039] Embodiment 3: Figure 1-6 As shown, the present invention also proposes a working method of a dust filter bag high-efficiency sewing device based on grain screening processing, comprising the following steps:

[0040] Step 1: Before sewing, one end of the filter bag is sleeved on the surface of a plurality of groups of support strips 54, and the part to be sewn faces the sewing machine head 3;

[0041] The second step is to start the electric telescopic rod 55 to push the fixed plate 56 to move in the direction away from the rotating plate 53. During the movement of the fixed plate 56, both ends of the movable plate 57 rotate and push the support bar 54 to drive the slider 59 to move along the slide groove 58 in the direction away from the fixed plate 56 until the filter bag is propped up and the seam is no longer in contact with the support bar 54. In the process of sleeve-fitting the filter bag on the surface of the support bar 54, one end of the filter bag is placed between the clamping plate 543 and the support bar 54 and pulled in the direction of the rotating plate 53. During this process, the filter bag drives the ball bearing 547 to rotate around the limit rod 546, and the support bar 54 is always fitted with the filter bag under the action of the torsion spring 544, so that the filter bag can be fixed and clamped and its flatness can be ensured, thereby reducing the probability of wrinkles at the seam due to the relative rotation of the filter bag and the support bar 54 during the rotation of the filter bag, thereby improving the seam quality.

[0042] Step three, put the bag bottom on the sewing table 4, start the electric telescopic rod 2 8, so that it pulls the slide plate 7 to pull the mounting plate 51 towards the sewing machine head 3, until the part to be sewn can be placed on the surface of the sewing table 4 and is directly below the needle of the sewing machine head 3, and the bottom edge of the bag is aligned with the part to be sewn of the filter bag, then start the motor 52 and the sewing machine body 2 at the same time, the sewing machine body 2 sews and traces the sewing part, and at the same time the output shaft of the motor 52 drives the rotating plate 53, the support bar 54 and the filter bag on its surface and the bag bottom to rotate one circle at the same frequency as the sewing machine body 2, completing the sewing of the bag bottom.

[0043] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification.
