Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-6, a steel strip unwinding device for strip brush production, including cross axle 1, the cover is equipped with interval adjustable first holding frame 2 and second holding frame 3 respectively on the cross axle 1, the centre gripping has the steel strip roll between first holding frame 1 and the second holding frame 2, first holding frame 2 and second holding frame 3 all include central disc 4, central disc 4 is around respectively fixedly connected with along its radial four pin 5 (being the cross distribution) that extend, four pin 5 of first holding frame 2 and second holding frame 3 are the setting of staggering each other, wherein all install the horizontal pole 6 that extends to second holding frame 3 on four pin 5 of first holding frame 2, the distance of horizontal pole 6 relative central disc 4 is adjustable, four horizontal poles 6 and the inner circle looks butt of steel strip roll, from the inboard tight steel strip roll that rises.

The utility model discloses in, the middle part of central disc 4 is equipped with the through-hole, fixedly connected with sleeve 7 on the inner wall of through-hole, and sleeve 7 suit is on cross axle 1. Thereby, the central disc 4 is sleeved on the transverse shaft 1, and the first clamping frame 2 and the second clamping frame 3 are sleeved on the transverse shaft 1.

The utility model discloses in, be equipped with rather than the communicating screw in inside on one side lateral wall of sleeve 7, have locking bolt 8 screw in screw, locking bolt 8 of screwing is fixed in on the cross axle 1 with central disc 4.

Therefore, by loosening the locking bolt 8, the central disc 4 can be moved along the length direction of the transverse shaft 1 (the axial direction of the transverse shaft 1), and the distance between the first clamping frame 2 and the second clamping frame 3 can be adjusted; the central disc 4 is fixed on the transverse shaft 1 by screwing the locking bolt 8, so that the first clamping frame 2 and the second clamping frame 3 with the adjusted intervals are fixed on the transverse shaft 1.

The utility model discloses in, four pin 5 of first holding frame 2 all are equipped with waist type through-hole 9 in the one end that is close to central disc 4.

The utility model discloses in, 6 cartridges of horizontal pole are equipped with screw thread section 10 in waist type through-hole 9 on the horizontal pole 6, and the outside spiral shell that closes at the place pin on the screw thread section 10 has screwed lock nut 11, and lock nut 11 screws, fixes horizontal pole 6 on the pin at place.

Therefore, the cross rod 6 can be moved along the length direction of the waist-shaped through hole 9 (the radial direction of the transverse shaft 1) by loosening the locking nut 11, so that the distance of the cross rod 6 relative to the central disc 4 can be adjusted; by screwing the locking nut 11, the cross rod 6 is fixed on the stop lever.

The utility model discloses in, the both ends of cross axle 1 are rotated respectively and are installed on support (not shown in the figure), realize the installation of whole unwinding device.

The invention is further described below with reference to the accompanying drawings:

the steel belt 12 used in the production process of the strip brush comprises a narrow belt 121 and spine parts 122 which are integrally connected with two sides of the narrow belt 121 and are distributed at intervals.

When the clamping device is used, the locking bolt 8 is unscrewed according to the width of the steel strip 12, the central disc 4 is moved adaptively along the length direction of the transverse shaft 1 (the axial direction of the transverse shaft 1), and the distance between the first clamping frame 2 and the second clamping frame 3 is adjusted to be matched with the width of the steel strip 12; and then the locking bolt 8 is screwed to fix the central disc 4 on the transverse shaft 1, so that the first clamping frame 2 and the second clamping frame 3 with the adjusted intervals are fixed on the transverse shaft 1.
