Description

Improved winding machine

Technical Field

The utility model relates to a modified rolling machine.

Background

In the stainless steel cold rolling industry, the rolling machine is indispensable equipment, and it mainly plays the effect and coils into the coil of strip with stainless steel band, convenient transportation and packing. Because the size and the type of the steel coil required by a customer are inconsistent, the inner diameter and the outer diameter of the steel coil are sometimes inconsistent during rolling, and the requirement of the customer can not be met due to the fact that the rolling inner diameter interval of the existing rolling machine is too small. There is therefore a need for improvements in winding machines to meet the needs of different customers.

SUMMERY OF THE UTILITY MODEL

In view of the above, the utility model provides a modified rolling machine, this modified rolling machine can increase the external diameter of the harmomegathus axle of rolling machine, adapts to the great coil of strip of internal diameter.

The utility model relates to a technical solution:

an improved winding machine comprises a rack, an expansion and contraction shaft, a driving device and a sleeve, wherein the expansion and contraction shaft is rotatably arranged on the rack, the driving device is used for driving the expansion and contraction shaft to rotate, the sleeve is sleeved on the periphery of the expansion and contraction shaft, and the peripheral wall of the sleeve is provided with a certain thickness so as to increase the outer diameter of the expansion and contraction shaft.

Further, the sleeve is an elastic sleeve.

Further, the shore hardness of the sleeve is 65 degrees.

Further, one end of the sleeve is provided with a contraction part matched with the outer end of the expansion and contraction shaft, and the outer diameter of the contraction part is gradually reduced towards the outside.

Furthermore, a pressing mechanism for pressing the steel coil on the expansion and contraction shaft is arranged on the rack.

Furthermore, hold-down mechanism includes pressure arm and compression roller, and pressure arm one end sets up in the frame swingably, and the compression roller is rotationally installed to the pressure arm other end.

Furthermore, hold-down mechanism includes support and swing driving piece, and the support is fixed in on the frame, and the swing driving piece is fixed in on the support, and the one end of pressure arm is fixed in on the output shaft of swing driving piece.

The utility model discloses modified rolling machine through set up the sleeve on the harmomegathus axle, under the prerequisite that does not change original harmomegathus axle construction, has increased the external diameter of harmomegathus axle through simple and feasible mode, can adapt to the great coil of strip of internal diameter, satisfies different customers' demand.

Drawings

Detailed Description

The technical solution in the embodiment of the present invention is clearly and completely described below with reference to the drawings in the embodiment of the present invention. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the invention.

Referring to fig. 1 and 2, the present invention provides an improved winding machine, which includes a frame 1, an expansion shaft 2 rotatably disposed on the frame 1, a driving device for driving the expansion shaft 2 to rotate, and a sleeve 3 sleeved on the periphery of the expansion shaft 2. The peripheral wall of the sleeve 3 has a certain thickness for increasing the outer diameter of the collapsible shaft 2, thereby adapting to the steel coil with larger inner diameter. The collapsible shaft 2 can be expanded or contracted inward toward the outer periphery to increase or decrease the outer diameter of the collapsible shaft 2. The collapsible shaft 2 is prior art and will not be described in detail herein.

Preferably, the sleeve 3 is an elastic sleeve with a shore hardness of 65 degrees, so that the elastic sleeve can elastically expand or contract when the collapsible shaft 2 expands or contracts.

Preferably, one end of the sleeve 3 has a contracting portion 31 matched with the outer end of the collapsible shaft 2, and the outer diameter of the contracting portion 31 is gradually reduced outwards, so that the upper and lower steel coils can play a guiding role.

In order to prevent the steel strip from loosening during the winding process, a pressing mechanism 4 for pressing the steel strip on the collapsible shaft 2 is further provided on the frame 1.

The pressing mechanism 4 comprises a support 41, a swinging driving member 42, a pressing arm 43 and a pressing roller 44, wherein the support 41 is fixed on the frame 1, the swinging driving member 42 is fixed on the support 41, one end of the pressing arm 43 is fixed on an output shaft of the swinging driving member 42, and the other end of the pressing arm 43 is rotatably provided with the pressing roller 44. In the winding process, the swing driving member 42 drives the pressing arm 43 to rotate by a certain angle, so that the pressing roller 44 presses the steel strip downwards to enable the steel strip to be wound more tightly.

The utility model discloses modified rolling machine through set up sleeve 3 on collapsible axle 2, under the prerequisite that does not change original collapsible axle structure, has increased collapsible axle 2's external diameter through simple and feasible mode, can adapt to the great coil of strip of internal diameter, satisfies different customers' demand.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all utilize the equivalent structure or equivalent flow transformation that the content of the specification does, or directly or indirectly use in other related technical fields, all including in the same way the patent protection scope of the present invention.
