Description

Technical Field

[0001] This utility model relates to the field of wrapping mold technology, and in particular to a wrapping mold that can test the wrapping tension. Background Technology

[0002] The existing method for testing the wrapping tension of wrapping dies involves testing the release tension of the strip, such as aluminum foil. This release tension is used as the wrapping tension during wrapping. However, from the start of the release to when the strip is wrapped around the cable, there are multiple frictional forces of varying magnitudes between the guide roller or guide wheel, between the strip and the guide roller, and between the guide wheels. These directly affect the wrapping tension. Therefore, using the measured release tension to represent the wrapping tension cannot accurately measure the wrapping tension during wrapping.

[0003] Therefore, how to provide a wrapping mold that can test wrapping tension, thereby greatly improving the accuracy of wrapping tension measurement and the ease of use of the wrapping mold, has become a technical problem that urgently needs to be solved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a wrapping mold that can test the wrapping tension, thereby improving the accuracy of wrapping tension measurement and the ease of use of the wrapping mold.

[0006] The device comprises two wrapping rods, four through-shaft annular pressure sensors, a wrapping mold base, a shaft pressure plate, a shaft baffle, and four hexagon socket screws. Each wrapping rod has a bearing at both ends, and the four through-shaft annular pressure sensors are respectively sleeved on the bearings of the two wrapping rods. The front end of the wrapping mold base has a groove, and the two wrapping rods are disposed in the groove. The shaft pressure plate is disposed above the groove by two hexagon socket screws. The shaft baffle is disposed at the front end of the wrapping mold base by two hexagon socket screws.

[0007] A baffle is provided at the middle of the wrapping mold base.

[0008] The front end of the groove has two upward-facing semi-circular notches, the radius of which is the same as the radius of the through-shaft annular pressure sensor, and the rear end of the groove has a shaft hole.

[0009] The rear end of the wrapping mold base is provided with a handle, and the handle is provided with a through hole.

[0010] The lower end of the axial pressure plate is provided with a downward-facing semi-circular notch, the radius of which is the same as the radius of the shaft hole. The left and right ends of the downward-facing semi-circular notch are respectively provided with a quarter-circle arc, the radius of which is the same as the radius of the shaft-penetrating annular pressure sensor.

[0011] The bearing has an inner diameter of 3mm, an outer diameter of 6mm, and a width of 2.5mm.

[0012] The through-shaft annular pressure sensor has an inner diameter of 6mm, an outer diameter of 10mm, a width of 10mm, and a measuring range of 0-1000g.

[0013] The advantages of this utility model are:
