Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The coil stock unreeling tension control device comprises a primary positioning mechanism, a fine positioning mechanism, a tension adjusting mechanism, a conical sleeve 6 and a coil stock 11.

The material roll 11 is sleeved outside the unwinding shaft 10. The material roll 11 is used for rolling material.

The conical sleeves 6 are arranged at two ends of the material roll 11. The conical sleeves 6 at the two ends of the material roll 11 clamp the material roll 11, so that the material roll 11 is coaxial with the unwinding shaft 10 and is arranged at a gap, and the conical sleeves 6 and the material roll 11 rotate synchronously.

The fine positioning mechanism comprises a bottom sleeve 3 and a bottom sleeve fastening bolt 4; the bottom sleeve 3 is sleeved on the unreeling shaft 10 and is positioned outside the conical sleeve 6; the conical sleeve 6 is rotatably arranged on the bottom sleeve 3. Preferably, the conical sleeve 6 is rotatably mounted on the bottom sleeve 3 through a rotating part 9; more preferably, the rotor 9 is a bearing. The bottom sleeve fastening bolt 4 is arranged on the bottom sleeve 3 in a threaded manner, and the end part of the bottom sleeve fastening bolt 4 is pressed against the unreeling shaft 10.

The tension adjusting mechanism comprises a limiting bolt 5, a pressure ring bolt 7 and a sliding ring 8; the slip ring 8 is arranged between the bottom sleeve 3 and the conical sleeve 6; the compression ring bolt 7 is arranged on the conical sleeve 6 in a threaded manner, and the end part of the compression ring bolt 7 is abutted against the sliding ring 8; the slip ring 8 is a circular ring provided with a notch, and the slip ring 8 is provided with a limiting hole 8a which penetrates through the slip ring in the radial direction; after the limiting bolt 5 penetrates through the conical sleeve 6, the end part of the limiting bolt is embedded in the limiting hole 8 a. The outer circumferential surface of the slip ring 8 is provided with a groove 8 b; the end part of the pressing ring bolt 7 is clamped in the groove 8 b.

The breach setting of sliding ring 8 makes things convenient for 8 covers of sliding ring to locate end cover 3, and makes things convenient for the internal diameter of adjustment sliding ring 8, is favorable to adjusting the frictional force of sliding ring 8 and end cover 3.

A stop hole 8a of the slip ring 8 is provided to limit axial displacement of the conical sleeve 6 relative to the bottom sleeve 3.

The recess 8b of sliding ring 8 sets up for when the toper cover 6 was rotatory, it was rotatory to drive sliding ring 8 through clamping ring bolt 7, thereby made sliding ring 8 rotatory on the end cover 3, then adjusted the frictional force between sliding ring 8 and the end cover 3 through clamping ring bolt 7, thereby adjusted tension.

The primary positioning mechanism comprises a fixed sleeve fastening bolt 1 and a fixed sleeve 2; the fixed sleeve 2 is sleeved on the unreeling shaft 10 and is positioned outside the bottom sleeve 3; the fixed sleeve 2 is in threaded connection with the bottom sleeve 3; the fixed sleeve fastening bolt 1 is installed on the fixed sleeve 2 in a threaded mode, and the end portion of the fixed sleeve passes through the fixed sleeve 2 to push the reel 10.

The working principle of the device is as follows: when tension needs to be adjusted after feeding, the conical sleeves 6 on the two sides are pushed by hand to support the material roll 11, and then the fixing sleeve 2 is fixed at the position of the unwinding shaft 10 by using the fixing sleeve fastening bolt 1, so that the coarse positioning of the whole device is realized.

Then the rotary bottom sleeve 3 is rotated, the position of the bottom sleeve 3 on the unreeling shaft 10 is finely adjusted, the tightness of the conical sleeve 6 against the material roll 11 is adjusted, and the position of the bottom sleeve 3 on the unreeling shaft 10 is fixed by a bottom sleeve fastening bolt 4, so that the fine positioning of the whole device is realized.

The friction between the slip ring 8 and the bottom casing 3 is then adjusted by means of the pressure ring bolts 7. Since the slip ring 8 rotates with the roll 11, the bottom cover 3 does not rotate. Therefore, by adjusting the friction between the slip ring 8 and the base 3, the tension of the material roll 11 can be adjusted.

The present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only for illustrating the principle of the present invention, without departing from the spirit and scope of the present invention, the present invention can also have various changes and improvements, and these changes and improvements all fall into the scope of the claimed invention.
