A kind of core pipe, as shown in Figure 1, including core tube body 1.Current most of core tube bodies 1 pass through with shaft
The mode of swelling provides biggish frictional force, to realize that shaft drives core tube body 1 to be rotated, this design can make to roll up
Core pipe ontology 1 is squeezed and deformed, so as to shorten the service life of core tube body 1.Therefore, it is opened at the both ends of core tube body 1
Equipped with U-shaped notch 11, the center line of a pair of U-shaped notch 11 is overlapped and parallel with 1 axis of core tube body.U-shaped notch 11 can
For the convex block inlay card being adapted in shaft with U-shaped notch 11, motor-driven rotatable shaft is rotated, and the convex block in shaft drives core tube body
1 rotation is made to be less prone to opposite sliding between core tube body 1 and shaft, be improved by the cooperation of convex block and U-shaped notch 11
Rolled product quality.
As shown in Fig. 2, the tube wall of core tube body 1 is located at U-shaped notch 11(referring to Fig. 1) opposite side is processed into plane
12, being recessed inwardly in plane 12 has accommodation groove 13, and several tension springs 131, one end of tension spring 131 and accommodation groove are equipped in accommodation groove 13
13 slot bottom is fixedly connected, and the other end is fixedly connected with circular arc block 2, and circular arc block 2, rolled product and core tube body 1 form one
A full circle.The starting point of rolled product is clamped between circular arc block 2 and core tube body 1, to realize rising for rolled product
The preliminary fixation at beginning makes the starting point of rolled product be not susceptible to overlapping and fold.
As shown in Fig. 2, plane 12 be located at 13 length direction of accommodation groove extended vertically positive stop strip 122, circular arc upwards
Being recessed inwardly on block 2 has the limiting slot 21 being adapted to positive stop strip 122.Using the cooperation of positive stop strip 122 and limiting slot 21, make circular arc
Block 2 is not easy to be subjected to displacement along its own length direction, so that circular arc block 2 and core tube body 1 is not susceptible to relative displacement, makes circular arc
Block 2, rolled product and core tube body 1 are always a full circle, to improve the quality of rolled product.In addition, positive stop strip
122 can keep out the starting point of rolled product, be not easily accessible it in accommodation groove 13, and the starting point of rolled product is protected not to be damaged
It is bad.This design method makes that rolled product can be clamped positioned at the two sides of accommodation groove 13 along its length, makes core pipe sheet
Body 1 is not influenced by own rotation direction, improves the applicability of core tube body 1.
As shown in Fig. 2, circular arc block 2 is recessed inwardly far from the side of core tube body 1 arc groove 22, set in arc groove 22
There is holding rod 221,221 upside of holding rod is flushed with circular arc block 2.Holding rod 221 can make circular arc block 2 more laborsaving when above mentioning,
It operates more convenient.
As shown in Figure 1, core tube body 1 and circular arc block 2 are made of hard material, hard material can make core tube body
1 and circular arc block 2 bending deformation is not susceptible to during long-time service, extend core tube body 1 and circular arc block 2 uses the longevity
Life.
