Description

Technical Field

[0001] The utility model relates to the technical field of cutting, in particular to a paper cutting device. Background Art

[0002] For the transformer product, insulating paper is required in multiple links during the production and processing. For example, when winding the coil of the transformer, insulating paper needs to be placed between the coil layers to play the role of insulation isolation. The insulating paper purchased on the market is generally in roll form and needs to be cut into square sheets by yourself. The square sheets of insulating paper can only be used in the coil after further processing. The method of cutting insulating paper is as follows: a scale is fixed on the surface of the platform, and the roll-shaped insulating paper is set on the platform. The staff holds the free end of the insulating paper and stretches the insulating paper along the scale; when the insulating paper is stretched to the preset length, the staff takes a long board and presses the long board against the insulating paper; the staff presses the long board with one hand and holds the blade with the other hand. The blade cuts the insulating paper along the long board to obtain a square sheet of insulating paper. The problem is: manual cutting of insulating paper is too inefficient. Utility Model Content

[0004] In order to achieve the purpose of this utility model, the following scheme is proposed:

The motor output shaft is connected to one of the gears. Two fixed plates are arranged at one end of the support plate facing the platform. The slide plate slides up and down to match the corresponding fixed plates. A blade is arranged at the position of the slide plate facing the gap. A second cylinder is arranged on the surface of the slide plate. The regulating rod is provided with a first strip groove and a second strip groove, which match the first cylinder and the second cylinder respectively. The end of the regulating rod away from the platform is rotatably connected to the support plate.

[0018] like Figure 1 As shown, this embodiment provides a paper cutting device, including a platform 1, a motor 2 and two cutting mechanisms symmetrically arranged up and down.

[0019] Specifically, Figure 1 , Figure 3 As shown, the platform 1 is provided with a gap 11 running through it, and the gap 11 is parallel to the short axis of the platform 1. An insulating paper roll 12 is mounted at one end of the platform 1, and the free end of the insulating paper is unfolded and laid flat on the platform 1, and the insulating paper covers the gap 11. A scale 15 is provided at one end of the platform 1 away from the insulating paper roll 12, and the scale 15 is used to facilitate the staff to stretch the insulating paper to a preset length.

[0020] In order to facilitate the staff to quickly stretch the insulating paper to a preset length, this embodiment adopts the following measures: Figure 1 , Figure 3As shown, a positioning mechanism 5 is further provided at one end of the platform 1 away from the insulating paper roll 12, and the positioning mechanism 5 includes a positioning plate 51, a screw rod 52 and a guide rod 53. The screw rod 52 and the guide rod 53 are arranged in parallel between the two base plates, and both ends of the screw rod 52 are rotatably connected to the two base plates respectively. One end of the screw rod 52 is connected to a hand wheel 54, and both ends of the guide rod 53 are fixedly connected to the two base plates respectively. The bottom surface of the positioning plate 51 is close to the platform 1, one end of the positioning plate 51 points to the scale 15, and the other end of the positioning plate 51 is threadedly connected to the screw rod 52, and at the same time slides with the guide rod 53.

[0021] When the staff member turns the hand wheel 54, the position of the positioning plate 51 can be moved. The distance between the positioning plate 51 and the gap 11 is the length of the insulation paper cut. When the insulation paper needs to be cut, the staff member holds the free end of the insulation paper and stretches the insulation paper to the positioning plate 51.

[0022] In order to make the insulating paper lay flatter on the platform 1, the present embodiment adopts the following measures: Figure 1 As shown, two bases 13 are provided on the top of the platform 1 , and a pressure roller 14 is rotatably provided between the two bases 13 . The pressure roller 14 is located between the insulating paper reel 12 and the gap 11 , and the insulating paper passes under the pressure roller 14 .

[0023] Specifically, Figure 1 , Figure 2 As shown, each cutting mechanism includes a gear 31, a regulating rod 32, a blade 33 and a slide plate 34. The motor 2 is arranged on one side wall of the support plate 4, and the gear 31 is rotatably arranged on the other side wall of the support plate 4. The two cutting mechanisms have two gears 31 in total, and the two gears 31 are meshed with each other. The output shaft of the motor 2 is connected to one of the gears 31. A first cylinder 311 is arranged at an eccentric position on the surface of the gear 31. Two fixed plates 41 are arranged at one end of the support plate 4 facing the platform 1. The two fixed plates 41 are respectively located above the platform 1 and below the platform 1. The slide plate 34 slides up and down to match the corresponding fixed plates 41. A blade 33 is arranged at the position of the slide plate 34 facing the gap 11. A second cylinder 341 is arranged on the surface of the slide plate 34. The regulating rod 32 is provided with a first strip groove 321 and a second strip groove 322. The first cylinder 311 matches the first strip groove 321, and the second cylinder 341 matches the second strip groove 322. The end of the regulating rod 32 away from the platform 1 is rotatably connected to the support plate 4. Figure 2 From the perspective, the two regulating rods 32 form a V-shaped structure, and the opening of the V-shaped structure faces the platform 1 .

[0024] The cutting principle is as follows: the staff stretches the insulating paper to the positioning plate 51; the motor 2 drives one of the gears 31, causing the two gears 31 to rotate synchronously. Under the action of the regulating rod 32, the rotation of the gear 31 will cause the two fixed plates 41 to gather together, that is, it will cause the two blades 33 to gather together; when the distance between the two first cylinders 311 is the smallest, the two blades 33 are closed at the gap 11, completing the cutting of the insulating paper and obtaining a square sheet of insulating paper.

[0025] In order to prevent the insulating paper from being dented at the gap 11 during the cutting process, the present embodiment takes the following measures: when the two blades 33 are closed at the gap 11 , the bottom surface of the blade 33 located at the upper layer is flush with the top surface of the platform 1 .

[0026] In the prior art, there are many ways to achieve the sliding plate 34 sliding up and down to fit the fixed plate 41. The specific implementation method of this embodiment is as follows: Figure 2 , Figure 3 As shown, a T-shaped slot 411 is provided on one side wall of the fixing plate 41 , and the T-shaped slot 411 penetrates downwardly through the fixing plate 41 . A T-shaped block 342 is provided on one side wall of the sliding plate 34 away from the second cylinder 341 , and the T-shaped block 342 is slidably fitted in the T-shaped slot 411 .

[0027] In summary, the present embodiment is provided with a scale 15 and a positioning mechanism 5, which facilitates the staff to quickly stretch the insulating paper to a preset length; the positioning plate 51 in the positioning mechanism 5 is adjustable so as to cut insulating paper of different lengths; the present embodiment is provided with two cutting mechanisms, and starting the motor 2 can cause the two blades 33 to close at the gap 11, thereby completing the cutting of the insulating paper and obtaining square sheets of insulating paper. This process eliminates the need for manual cutting of insulating paper, saves time and effort, and improves efficiency.

[0028] The above embodiments are only used to illustrate the technical ideas and features of the utility model, and are not intended to be the only or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
