Description

Technical Field

[0001] The invention relates to the field of material mechanical property testing, and in particular to an insulating sleeve drawing and cutting device and a use method thereof. Background Art

[0002] The power and communication industries are one of the main application areas of insulating sleeves. In the power industry, insulating sleeves are used to protect cables and wires to prevent current leakage and protect the safety of personnel and equipment. At the same time, insulating sleeves can also prevent cables or wires from being affected by the external environment, such as water, oil, chemicals, etc., to ensure the normal service life of cables or wires. In the communication industry, insulating sleeves are used to protect optical cables and communication cables to prevent signal interference and attenuation. Since insulating sleeves have such a wide range of applications in modern society, their demand is also very huge.

[0003] However, since a coil of casing is usually hundreds of meters or even thousands of meters, if it is cut into the required length manually, the shape of the cut will vary due to work experience and the cutting accuracy will be difficult to control. The manual cutting method is not only time-consuming and labor-intensive, but also has low production efficiency and high production costs.

[0004] In order to solve the above-mentioned technical problems of cutting, application number CN202022723474.2 (glass fiber tube production device) proposes a glass fiber pipe cutting production equipment, in which one end of the glass fiber tube is fixed and the other end is driven by a slider to move the glass fiber tube toward the cutting frame. When the distance measuring sensor detects the set distance, the other end is pressed for cutting. However, the scheme does not specifically introduce whether multiple glass fiber tubes can slide at the same time and whether they can be cut individually. In addition, the slider has to move back and forth, and the working efficiency is low; CN2021121964422.2 (a glass fiber rolling tube cutting tool) drives the screw to rotate through a stepper motor, and the screw drives the slide to adjust the spacing between the cutting blades, thereby realizing the fixed-length interception of the glass fiber tube, but this distance determination method has low accuracy and cannot achieve precise distance determination. In summary, the existing technology still has the following problems: 1. The same set of equipment cannot achieve single cutting and batch cutting at the same time; 2. The cutting method is complicated, the operation is difficult, and fast cutting cannot be achieved; 3. No traction device is provided during cutting, and bending and twisting are prone to occur before cutting. Summary of the invention
