[0014] A method for using a motor core insulation paper flattening device comprises the following steps: Step 1: The insulating paper is conveyed through the gap between the placement roller and the moving roller, and the insulating paper is initially flattened by the two rollers. The moving roller is pushed to move to adapt to the insulating paper of different thicknesses. The rotation of the rotating rod is limited by the positioning rod. The calibration rod and the docking rod are used to achieve a balancing effect when adjusting the positions of the moving rollers on both sides, so as to ensure that the moving rollers maintain the same position and pressure when moving up and down; Step 2: Clean the impurities on the surface of the insulating paper by using a brush rod, and use an air pump to make the air gun suck the impurities generated by the brush rod into the storage box for storage, and make the preheating roller contact with the insulating paper to make the material of the insulating paper soft and plastic, so as to facilitate subsequent flattening, and heat the pressing plate by a heating plate to flatten the insulating paper; Step 3: The pressing plate is lowered to drive the L-shaped rod to move, so that the roller rod moves upward to support the flattened area. The flattened insulating paper is transported to the collection rack, and the stacked insulating paper is aligned by the alignment plate.

[0015] The present invention provides a device and method for flattening the insulation paper of a motor core, which has the following beneficial effects: (1) The present invention, through the setting of the pretreatment device, conveys the insulating paper through the gap between the moving roller and the placing roller. At this time, the insulating paper will be flattened by the moving roller and the placing roller. When it is necessary to pretreatment the insulating paper of different thicknesses, the insulating paper of different thicknesses can be adjusted and flattened by rotating the rotating rod in cooperation with the spiral groove 1, the sliding block and the moving roller. By adjusting the distance between the moving roller and the insulating paper, the applied pressure can be adjusted according to the thickness change of the insulating paper to prevent overpressure or underpressure. Appropriate pressure helps to remove bubbles and wrinkles and avoid damage to the insulating paper. The positioning rod is used to prevent external force from accidentally touching the rotating rod and causing adjustment errors. Because the sliding blocks on both sides need to be adjusted, the adjustment on both sides may be unbalanced. At this time, the calibration rod is used in cooperation with the triangular block, the docking rod and the No. 1 spring to balance the adjustment on both sides, which can ensure that the moving roller maintains the same position and pressure when moving up and down, which helps to achieve uniform flattening of the surface of the insulating paper and reduce wrinkles or damage caused by uneven pressure.

[0016] (2) The invention, through the setting of a flattening device, cleans the surface of the insulating paper through a brush plate rod, and sucks in impurities generated by the brush plate rod cleaning through an air pump working in conjunction with an air suction gun, and transports them to a storage box through a pipeline. Timely removal of impurities on the insulating paper can reduce the embedding of these impurities into the insulating material in subsequent processes, thereby improving the quality of the final product. At this time, the insulating paper continues to be transported, and the preheating roller generates heat through the sliding button in conjunction with the heating rod and heating element 1. The preheating roller rolls on the surface of the insulating paper through the movement of the sliding button. Preheating can make the material of the insulating paper soft and plastic. The pressing plate is heated by the servo motor in conjunction with the electric push rod, the heating plate and the heating element 2, so that it is easier to be flattened and shaped when in contact with the insulating paper, thereby obtaining a smoother surface.

[0017] (3) In the present invention, flattening on the conveyor belt may cause deformation of the conveyor belt through the setting of the discharging device, and the hollow part in the middle of the conveyor belt cannot be supported when flattening. At this time, the insulating paper is supported when flattening by the gear, rack rod, connecting frame and roller rod. Without the support of the roller rod, the conveyor belt may bend or wave during operation, which will cause the insulating paper to fail to obtain consistent pressure during the flattening process, thereby affecting the flattening effect and the final quality of the insulating paper. The flattened insulating paper is transported to the collection rack through the guide plate, and the stacked insulating paper is aligned by the screw rod 2, brake rod and alignment plate. Alignment helps to maintain the flatness of the insulating paper, which is very important for subsequent processing steps, such as cutting and laminating, and can ensure the consistency and quality of the product. The aligned insulating paper can be taken out by sliding the sliding plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] A method for using a motor core insulation paper flattening device comprises the following steps: Step 1: The insulating paper is conveyed through the gap between the placement roller 13 and the moving roller 16, and the insulating paper is preliminarily flattened by the two, and the moving roller 16 is pushed to move to adapt to insulating papers of different thicknesses, and the rotation of the rotating rod 17 is limited by the positioning rod 19. The calibration rod 110 and the docking rod 111 are used to achieve a balancing effect when adjusting the positions of the moving rollers 16 on both sides, so as to ensure that the moving rollers 16 maintain the same position and pressure when moving up and down; Step 2: Clean the impurities on the surface of the insulating paper by the brush plate rod 24, and use the suction pump 232 to make the suction gun 233 suck the impurities generated by the brush plate rod 24 into the storage box 231 for storage, and make the preheating roller 21 contact with the insulating paper to make the material of the insulating paper soft and plastic, so as to facilitate subsequent flattening, and heat the pressing plate 29 by the heating plate 210 to flatten the insulating paper; Step three: The pressing plate 29 is lowered to drive the L-shaped rod 211 to move, so that the roller rod 32 moves upward to support the flattened area. The flattened insulating paper is transported to the collection rack 33, and the stacked insulating paper is aligned by the alignment plate 36.

[0025] When the present embodiment is working, the placing roller 13 is driven to rotate by the rotating motor 12, and the moving roller 16 is driven to rotate by the rotating motor 2 15.

The rotating roller 3 rotates through the No. 1 belt to drive the screw rod 113 to rotate, and the rotation of the screw rod 113 drives the spiral groove 2 to rotate.

Quality, at this time, the insulating paper continues to be conveyed, and the sliding button 114 moves the heating rod 20, and the preheating roller 21 generates heat through the heating element 1. The preheating roller 21 rolls on the surface of the insulating paper through the movement of the sliding button 114. Preheating can make the insulating paper material soft and plastic. The output end of the electric push rod 28 is driven by the servo motor 27 to move, and the output end of the electric push rod 28 moves to drive the pressing plate 29 to move, and the pressing plate 29 moves to drive the L-shaped rod 211 to move, and the L-shaped rod 211 moves to drive the rack block to move. The rack block moves and contacts with the gear 212 to make the gear 212 rotate. The pressing plate 29 is heated by the heating element 2 of the heating plate 210, so that it is easier to be flattened and shaped when in contact with the insulating paper, thereby obtaining a smoother surface; Flattening the conveyor belt 2 may cause deformation of the conveyor belt 2, and the hollow part in the middle of the conveyor belt 2 cannot be supported during flattening.

The roller rod 32 moves to contact and rotate with the inner wall of the conveyor belt 2, so that the insulating paper is supported when flattening. Without the support of the roller rod 32, the conveyor belt 2 may bend or wave during operation, which will cause the insulating paper to be unable to obtain consistent flatness during the flattening process. The pressure of the insulating paper affects the flattening effect and the final quality of the insulating paper. The flattened insulating paper is transported to the collecting rack 33 through the guide plate 37, and the brake rod 35 is driven to move by the rotation of the screw rod 213. The movement of the brake rod 35 drives the alignment plate 36 to move. The movement of the alignment plate 36 will contact the edge of the insulating paper so that the stacked insulating paper is aligned. Alignment helps to maintain the flatness of the insulating paper, which is very important for subsequent processing steps, such as cutting and compounding, and can ensure the consistency and quality of the product. The aligned insulating paper can be taken out by sliding the sliding plate 34.
