Technical Field

[0001] This utility model relates to the technical field of insulating tape cutters, and in particular to an electrical automation insulating tape cutter. Background Technology

[0002] Insulating tape specifically refers to the tape used by electricians to prevent electrical leakage and provide insulation. Also known as insulating cloth or tape, it consists of a base tape and a pressure-sensitive adhesive layer. The base tape is generally made of cotton cloth, synthetic fiber fabric, or plastic film, while the adhesive layer is made of rubber with tackifying resins and other compounding agents, resulting in good adhesion and excellent insulation performance. Insulating tape possesses good insulation, voltage resistance, flame retardancy, and weather resistance, making it suitable for wire splicing and electrical insulation protection.

[0003] When repairing cables of electrical automation equipment, insulating tape is needed to wrap the cables. To facilitate cutting the insulating tape, a cutting device is required. However, some existing cutting devices do not adequately protect the cutting blade during use, which can easily lead to accidental hand injuries when the user touches the blade.

[0004] To address the aforementioned issues, an electrically automated insulating tape cutter is proposed. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an electrical automation insulating tape cutter that can solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electrical automation insulating tape cutter, comprising a housing, a rotating column rotatably connected inside the housing, four clamping plates slidably connected inside the rotating column, springs fixedly installed on one end of each of the four clamping plates inside the rotating column, and the ends of the four springs away from the four clamping plates being fixedly connected to the interior of the rotating column, with one side of each of the four clamping plates being inclined.

[0007] Preferably, a protective cover is provided on one side of the outer casing.

[0008] Preferably, a second slide is provided on one side of the outer casing, and a spring is slidably connected inside the second slide.

[0009] Preferably, a fixing rod is fixedly installed inside the second slide rail, the surface of the fixing rod is slidably connected to the inside of the protective cover, and a spring is movably sleeved on the surface of the fixing rod.

[0010] Preferably, the protective cover has two sliding rods slidably connected inside, both of which slide through the protective cover and extend to the bottom of the protective cover, and a cutting blade is fixedly installed at the bottom of the two sliding rods.

[0011] Preferably, a connecting plate is fixedly installed on the upper end of the two slide rods, and a return spring is movably sleeved on the surface of each of the two slide rods. The upper ends of the two return springs are fixedly connected to the two connecting plates respectively, and the lower ends of the two return springs are fixedly connected to the protective cover.

[0012] Preferably, a limiting rod is fixedly installed on one side of the outer shell, a pressing plate is rotatably connected to the top of the connecting plate, a first slide rail is provided on one side of the pressing plate, and the limiting rod is slidably connected inside the first slide rail.

[0013] Preferably, a support plate is fixedly installed on one side of the outer shell, and a knife groove is formed on the top of the support plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0026] Please see Figure 1-5 This utility model provides a technical solution: an electrical automation insulating tape cutter, including a housing 1, a rotating column 13 rotatably connected inside the housing 1, four clamping plates 14 slidably connected inside the rotating column 13, and springs 18 fixedly installed on one end of each of the four clamping plates 14 inside the rotating column 13. The ends of the four springs 18 away from the four clamping plates 14 are fixedly connected to the inside of the rotating column 13, and one side of each of the four clamping plates 14 is inclined.

[0027] Align the insulating tape roll with the rotating column 13, then squeeze the insulating tape roll, and then squeeze the inclined surfaces of the four clamping plates 14, causing the four clamping plates 14 to slide into the rotating column 13 and squeeze the four springs 18. Then, the elastic force of the four springs 18 causes the four clamping plates 14 to squeeze and fix the insulating tape roll, which facilitates the fixing of the insulating tape roll and improves the convenience of fixing.

[0028] A protective cover 2 is provided on one side of the outer casing 1.

[0029] The protective cover 2 facilitates the restriction of the insulating tape roll, thereby improving the protection effect of the insulating tape roll.

[0030] A second slide rail 15 is provided on one side of the outer casing 1. A spring spring 17 is slidably connected inside the second slide rail 15. A fixing rod 16 is fixedly installed inside the second slide rail 15. The surface of the fixing rod 16 is slidably connected to the inside of the protective cover 7. A spring spring 17 is movably sleeved on the surface of the fixing rod 16. The upper end of the spring spring 17 is fixedly connected to the protective cover 7, and the lower end of the spring spring 17 is fixedly connected to the inner wall of the second slide rail 15. Two slide rods 10 are slidably connected inside the protective cover 7. Both slide rods 10 slide through the protective cover 7 and extend to the bottom of the protective cover 7. The bottom of the two slide rods 10... A cutting blade 12 is fixedly installed. A connecting plate 6 is fixedly installed on the upper end of two sliding rods 10. A return spring 11 is movably sleeved on the surface of each of the two sliding rods 10. The upper ends of the two return springs 11 are fixedly connected to the two connecting plates 6 respectively. The lower ends of the two return springs 11 are fixedly connected to the protective cover 7. A limiting rod 5 is fixedly installed on one side of the outer shell 1. A pressing plate 3 is rotatably connected to the top of the connecting plate 6. A first slide 4 is opened on one side of the pressing plate 3. The limiting rod 5 is slidably connected inside the first slide 4. A support plate 8 is fixedly installed on one side of the outer shell 1. A blade groove 9 is opened on the top of the support plate 8.

[0031] Pressing the pressing plate 3 causes it to squeeze the connecting plate 6. As the connecting plate 6 moves downward, the limiting rod 5 slides inside the first slide rail 4. Since the elastic force of the two return springs 11 is greater than that of the elastic spring 17, the protective cover 7 slides on the second slide rail 15 and the fixing rod 16 when the connecting plate 6 is squeezed. The protective cover 7 squeezes the elastic spring 17, which in turn makes contact with the surface of the support plate 8, fixing the insulating tape on the support plate 8. As the connecting plate 6 is continuously squeezed, the protective cover 7 stops descending and contacts the support plate 8. The connecting plate 6 then squeezes the two sliding rods 10, causing them to slide inside the protective cover 7 and squeeze the two return springs 11. This causes the cutting blade 12 to move downward, cutting the insulating tape and improving the ease of cutting the insulating tape.

[0032] When the pressure plate 3 is not pressed, the protective cover 7 will be reset by the elastic force of the spring spring 17, and the connecting plate 6 and the cutting blade 12 will be reset by the elastic force of the reset spring 11. This will cause the cutting blade 12 to retract into the interior of the protective cover 7, thereby facilitating the protection of the protective cover 7, preventing the operator from touching the cutting blade 12, improving the safety of the device and avoiding injury.

[0033] Working principle:

[0034] Align the insulating tape roll with the rotating column 13, then squeeze the insulating tape roll, thereby squeezing the inclined surfaces of the four clamping plates 14, causing the four clamping plates 14 to slide inwards towards the rotating column 13, and squeezing the four springs 18. The elastic force of the four springs 18 then causes the four clamping plates 14 to squeeze and fix the insulating tape roll. Press the pressing plate 3, causing it to squeeze the connecting plate 6. As the connecting plate 6 moves downwards, the limiting rod 5 slides inside the first slide rail 4. Since the elastic force of the two return springs 11 is greater than the elastic force of the spring spring 17, the limiting rod 5 slides inside the first slide rail 4. When the connecting plate 6 is pressed, the protective cover 7 slides on the second slide rail 15 and the fixing rod 16, and the protective cover 7 presses against the spring spring 17, which in turn makes the protective cover 7 contact the surface of the support plate 8 and fixes the insulating tape on the support plate 8. As the connecting plate 6 is continuously pressed, the protective cover 7 no longer descends from the support plate 8, which causes the connecting plate 6 to press against the two slide rods 10, which in turn makes the two slide rods 10 slide inside the protective cover 7 and press against the two return springs 11, which in turn causes the cutting blade 12 to move downward and cut the insulating tape.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
