Moreover, the equipment has a simple structure, the assemblies are sequentially arranged, and the volume of the equipment is effectively reduced.

[0033] Referring to Figure 1 The feeding assembly 1 comprises a base 11, and the base 11 is placed on the ground. A rotating disc 12 is arranged at the top end of the base 11, the rotating disc 12 is rotationally connected with the base 11 through a rotating shaft, and the rotating disc 12 rotates in the horizontal plane. A support column 13 is vertically arranged at the center of the top surface of the rotating disc 12, and the support column 13 is connected with the rotating disc 12 through welding.

[0034] An operator directly puts the copper pipe roll on the support column 13, and during production, the rotating disc 12 rotates to feed under the pulling force of the calendering assembly 3 and the winding piece 41. The feeding assembly 1 has a simple structure and low equipment cost.

[0035] Referring to Figure 1 The deviation rectifying assembly 2 comprises a pair of guide rollers 21, the two guide rollers 21 are rotationally connected with the rack 6 and are arranged at the edges of the rack 6 close to the base 11. The axial directions of the two guide rollers 21 are both arranged in the horizontal direction and are perpendicular to the moving direction of the copper pipe, and the two guide rollers 21 are arranged in the vertical direction. The copper pipe passes between the two guide rollers 21.

[0036] The two rows of deviation correction wheels 22 are located on the sides of the copper pipe, and the two rows of deviation correction wheels 22 are staggered and the copper pipe passes between the two rows of deviation correction wheels 22. The midpoint of the connecting line of the two guide rollers 21 is aligned with the midpoint in the thickness direction of the deviation correction wheel 22.

[0037] The copper pipe passes between the two guide rollers 21, and the two guide rollers 21 correct the shape of the copper pipe in the vertical direction; the copper pipe passes between the two rows of deviation correction wheels 22, and the two rows of deviation correction wheels 22 correct the shape of the copper pipe in the horizontal direction. By setting the guide rollers 21 and the deviation correction wheels 22, the copper pipe is corrected before rolling, improving the quality of rolling.

[0038] Referring to Figure 2 and Figure 3 , the rolling assembly 3 includes a first rolling wheel 31 and a second rolling wheel 32, and the axis directions of the first rolling wheel 31 and the second rolling wheel 32 are both arranged in the horizontal direction perpendicular to the moving direction of the copper pipe. The first rolling wheel 31 is installed on the output shaft of the rolling drive motor 5 by bolts, and bearings are installed at both ends of the first rolling wheel 31, and the first rolling wheel 31 is rotatably connected to the rack 6 through the bearings. Bearings are also installed at both ends of the second rolling wheel 32, and the bearings at both ends of the second rolling wheel 32 are connected with the jacking bolts 33, one end of the jacking bolts 33 away from the second rolling wheel 32 is threadedly connected with the rack 6, and the jacking bolts 33 are arranged in the vertical direction and can control the distance between the first rolling wheel 31 and the second rolling wheel 32.

[0039] The operator controls the distance between the first rolling wheel 31 and the second rolling wheel 32 by adjusting the jacking bolts 33, and during rolling, the rolling drive motor 5 drives the first rolling wheel 31 to rotate, the first rolling wheel 31 rotates to drive the copper pipe to move, and the second rolling wheel 32 rotates in the opposite direction of the first rolling wheel 31 under the action of the copper pipe. The first rolling wheel 31 and the second rolling wheel 32 roll the copper pipe into a copper belt and deliver the copper belt to the direction of the winding member 41.

[0040] Referring to Figure 2 and Figure 3The winding driving member 42 comprises a first driven wheel 421 and a second driven wheel 422, both of which are rotationally connected to the frame 6 through a rotating shaft and are located on the side of the frame 6 close to the calender driving motor 5. The first driven wheel 421 is driven by the output shaft of the calender driving motor 5 through a belt, and the second driven wheel 422 is driven by the first driven wheel 421 through a chain. A friction wheel 423 is sleeved on the second driven wheel 422, and the chain is sleeved on the outer side wall of the friction wheel 423. The chain is in clamping connection with the outer side wall of the friction wheel 423. The friction wheel 423 drives the second driven wheel 422 to rotate through friction, and the friction wheel 423 and the second driven wheel 422 can slide relative to each other. The second driven wheel 422 is connected to the winding member 41 through a shaft rod, and the winding member 41 is arranged on the other side of the frame 6.

[0041] The winding member 41 comprises a winding wheel 411, which is coaxially arranged with the second driven wheel 422 and rotationally connected to the frame 6 through the same shaft rod. The winding wheel 411 is fixedly connected to the shaft rod of the second driven wheel 422 through a bolt, and the winding wheel 411 and the second driven wheel 422 rotate synchronously. Two winding discs 412 are sleeved on the outer side wall of the winding wheel 411, and are arranged along the axial direction of the winding wheel 411. The distance between the two winding discs 412 is adapted to the width of the copper strip. The winding disc 412 close to the second driven wheel 422 is fixedly connected to the winding wheel 411 through welding, and the other winding disc 412 is detachably connected to the winding wheel 411 through a bolt.

[0042] A plurality of limiting plates 413 are mounted on the winding disc 412 and are arranged along the circumferential direction of the winding disc 412. The limiting plates 413 are mounted on the side walls of the two winding discs 412 close to each other, and the copper strip is clamped between the limiting plates 413. The side walls of the limiting plates 413 close to each other can limit the position of the copper strip. The length direction of the limiting plate 413 is arranged along the radial direction of the winding disc 412. One end of the limiting plate 413 away from the center of the winding disc 412 protrudes from the edge of the winding disc 412. The protruding ends of the corresponding two limiting plates 413 on the two winding discs 412 are bent away from each other, so as to guide the copper strip into the winding disc 412.

[0043] The operator detaches the winding disc 412 away from the second driven wheel 422, fixes the front end of the rolled copper strip on the winding wheel 411, and then reattaches the winding disc 412. The rolling drive motor 5 drives the first driven wheel 421 to rotate, and the first driven wheel 421 drives the friction wheel 423 to rotate. At this time, the copper strip on the winding wheel 411 is less, and the reaction force of the copper strip on the winding wheel 411 is small. The friction wheel 423 drives the second driven wheel 422 to rotate synchronously. The copper strip is continuously wound on the winding wheel 411, and the copper strip outside the winding disc 412 first contacts the bending section of the limiting plate 413 when entering, and the limiting plate 413 guides the copper strip to enter the winding disc 412, while limiting the subsequent copper strip to be wound outside the previous copper strip. As the copper strip on the winding wheel 411 increases, the radius of the copper strip roll increases, and the reaction force of the copper strip on the winding wheel 411 gradually increases. When the reaction force of the copper strip on the winding wheel 411 is greater than the maximum static friction force of the friction wheel 423 on the second driven wheel 422, the friction wheel 423 and the second driven wheel 422 slide relative to each other, avoiding the copper strip from being torn, and performing overload protection. When enough copper strip is collected on the winding wheel 411, the operator turns off the rolling drive motor 5, cuts and fixes the copper strip, then detaches the winding disc 412 away from the second driven wheel 422, takes out the copper strip roll for storage, and then performs subsequent rolling.

[0044] By setting the winding drive member 42 in linkage with the rolling drive motor 5, the cost of the equipment is reduced. By setting the friction wheel 423 for overload protection, compared with the prior art setting of a speed reducer to slow down the power source, the equipment volume is saved, and the equipment cost is reduced. The winding disc 412 and the limiting plate 413 are simple in structure, space-efficient, and low in cost.

[0045] The implementation principle of the copper strip rolling equipment in the embodiment of the application is as follows: the copper pipe is rectified by the guide roller 21 and the deviation rectifying wheel 22 after leaving the rotating disc 12, and then enters between the first rolling wheel 31 and the second rolling wheel 32 to be rolled into a copper strip. Subsequently, the copper strip is guided and wound on the winding wheel 411 by the winding disc 412 and the limiting plate 413. By setting the winding drive member 42 in linkage with the rolling drive motor 5, the cost of the equipment is reduced. By setting the friction wheel 423 for overload protection, compared with the prior art setting of a speed reducer to slow down the power source, the equipment volume is saved, and the equipment cost is reduced. The winding disc 412 and the limiting plate 413 are simple in structure, space-efficient, and low in cost.

[0046] The above are preferred embodiments of the application, which do not limit the protection scope of the application. Therefore, any equivalent changes made on the basis of the structure, shape, and principle of the application should be covered by the protection scope of the application.
