[0028] Compared with the prior art, the portable insulating paper creasing machine described in the embodiment of the utility model has the following advantages:

[0029] In the portable insulating paper creasing machine provided by the embodiment of the utility model, when the creasing operation is required, the hand presses down the pressing handle 44 to drag it, compresses the spring sheet 43, and makes the entire creasing device 4 sink, and the creasing wheel 41 can roll on the insulating paper and press out creases, and avoid scratching the surface of the insulating paper; in other words, the portable insulating paper creasing machine provided by the embodiment of the utility model can perform single-mark creasing on the insulating paper through one adjustment, can produce the same type of insulating paper through one adjustment, and can perform distributed creasing work on complex insulating paper shapes. By replacing the creasing wheel with a paper cutting wheel, the insulating paper can also be fixed in length. Therefore, the portable insulating paper creasing machine provided by the embodiment of the utility model can effectively reduce the operating convenience of the insulating paper creasing work, and effectively improve production efficiency and reduce production costs.

[0030] Among them, Figure 4 As shown, the spring sheet 43 may include: a T-shaped portion 431 having a central circular through hole, and an arched portion 432 vertically connected to both sides of the T-shaped portion 431; the two arched portions 432 are symmetrically distributed along the vertical direction of the T-shaped portion 431, and the arched portion 432 is a pointed Ω-shaped structure.

[0032] The following is a detailed description of the use of the portable insulating paper creasing machine provided by the embodiment of the utility model in conjunction with the accompanying drawings:

[0033] First, according to the thickness of the insulating paper, the height of the support plug plate 31 is adjusted, and then the distance between the indentation wheel 41 and the upper surface of the base 1 is adjusted. After adjustment, the screws are locked to fix the slide rail support mechanism 3; then the lead screw 21 is driven to rotate by rotating the indexing hand wheel 25, and the lead screw 21 and the slider 22 are linked through the spiral mechanism to adjust the position of the slider 22, and then the distance between the paper baffle 26 and the indentation wheel 41 is adjusted to adjust the indentation position of the insulating paper; then the insulating paper is put in, one side of the insulating paper is against the paper baffle 26, and the pressing handle 44 is pressed down by hand to compress the spring sheet 43 so that the indentation wheel 41 is pressed onto the insulating paper, and at the same time, the indentation device 4 is dragged along the slide rail 32 to roll a crease on the insulating paper; then the same type of insulating paper is put in for indentation operation, and the indentation position can be adjusted after completion, and the above action is continued to be repeated to complete the indentation work of the entire insulating paper; after the operation is completed, the pressing handle 44 is released, and the spring sheet 43 lifts up the entire indentation device 4 by elastic force, so that the indentation wheel 41 is separated from the insulating paper, and the insulating paper with completed indentation can be taken out.

[0034] In summary, the portable insulating paper creasing machine provided by the embodiment of the utility model mainly has the following advantages:

[0035] 1. The spring sheet used is formed by integral stamping of beryllium bronze sheet, with good structural rigidity, wear and corrosion resistance, strong environmental adaptability, low cost and wide application;

[0036] 2. The relative movement between the indentation wheel and the insulating paper is rolling contact, which is less damaging to the surface of the insulating paper than sliding contact, and can significantly reduce the insulation performance defects of the motor. It is compatible with more types of insulating paper of different materials and thicknesses, and has a wide range of applications.

[0037] 3. The indentation device uses the elastic force of the spring sheet to lift the entire indentation device so that the indentation device can be separated from the insulating paper, which is convenient for replacing or adjusting the insulating paper; the indentation wheel and the pin shaft are supported by bearings to ensure that there is minimal friction resistance between the indentation wheel and the pin shaft, ensuring that the indentation wheel and the insulating paper can be in rolling contact without sliding contact, scratching the insulating paper, and causing hidden dangers to the motor insulation;

[0038] Fourth, the screw stop mechanism uses a handwheel to adjust the position of the slider on the screw, which in turn drives the paper stopper to move. The position can be adjusted according to the indentation size of the insulating paper, so that the indentation size accuracy of the insulating paper can be greatly improved. The indentation device can improve the indentation accuracy through the slide rail limiter. These two methods can improve the indentation accuracy together.

[0039] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
