DESCRIPTION OF THE EMBODIMENTS

(11) Various embodiments of the present disclosure will be disclosed below by way of illustration, and for the sake of clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit the present disclosure. That is, in some embodiments of the present disclosure, these practical details are not necessary. Additionally, in order to simplify the drawings, some conventional structures and components will be illustrated in a simplified and schematic manner.

(12) Additionally, the description of “first”, “second” and the like in the present disclosure is merely for the purpose of description and are not intended to be indicate the order or the sequence, nor are they intended to limit the present disclosure. It is merely for distinguishing components or actions described in the same technical terms, and cannot be understood as indicating or implying its relative importance or implicitly indicating the number of technical features indicated. Thus, features defined with “first” and “second” may include at least one of said features, either explicitly or implicitly. In addition, the technical solutions between the various embodiments can be combined to each other, but this must be based on the ability of ordinary skilled in the art to achieve. When a combination of technical solutions conflicts or cannot be achieved, it should be considered that this combination of technical solutions does not exist, nor is it within the scope of protection claimed by the present disclosure.

(13) Please refer to FIGS. 1-8. A winding core tube with a uniformly rough surface of the present disclosure includes a rotary barrel 01. A circular through hole is provided at the inner side of the rotary barrel 01, a rotating sleeve 06 is fixedly connected at the circular through hole of the rotary barrel 01, a circular through hole is provided at the outer side of the rotating sleeve 06, and a connecting shaft 05 is fixedly connected at the circular through hole of the rotating sleeve 06. The length of the connecting shaft 05 is greater than that of the rotary barrel 01, sprayed particles 02 are sprayed on the outer side of the rotary barrel 01, and copper and aluminum foil 07 is sleeved on the outer side of the rotary barrel 01. A left side baffle 03 is provided at the left side of the rotary barrel 01, an annular groove is provided at the inner side of the left side baffle 03, and the rotary barrel 01 is rotatably connected to the annular groove of the left side baffle 03. A right side baffle 04 is provided at the right side of the rotary barrel 01, an annular groove is provided at the inner side of the right side baffle 04, the right side of the rotary barrel 01 is rotatably connected to the annular groove of the right side baffle 04, and the right side baffle 04 has the same size and diameter as the left side baffle 03. The sprayed particles 02 are provided to enable the friction in copper and aluminum foil winding to increase when the copper and aluminum foil is wound by means of the rotary barrel 01, so that the copper and aluminum foil, when being wound into a roll, can better avoid the occurrence of wrinkles, while the copper and aluminum foil is prevented from slipping after its winding, resulting in more stability in copper and aluminum foil winding.

(14) The diameter range of the sprayed particles 02 is 2-15 ym, the surface of the rotary barrel 01 is sprayed with a reinforcement agent, the sprayed particles 02 and the reinforcement agent adhere to each other, and the sprayed particles 02 are irregular in shape. The cooperation between the reinforcement agent and the sprayed particles 02 enables the sprayed particles 02 to attach to the rotary barrel 01 more stably, so that the sprayed particles 02 can function successfully.

Embodiment 1

(15) Referring to FIG. 5, the diameter range of the sprayed particles 02 is set to 2-8 ym. Where copper and aluminum foil with a thickness of less than 6 ym is wound, the friction coefficient when the copper and aluminum foil just contacting the sprayed particles 02 is a low coefficient of friction compared to the case without providing sprayed particles 02, which facilitates smoothing and flattening of the copper and aluminum foil, and helps to start up the copper and aluminum foil winding.

Embodiment 2

(16) Referring to FIG. 6, the diameter range of the sprayed particles 02 is set to 9-15 ym. Where copper and aluminum foil with a thickness of more than 6 ym is wound, because of a large spacing between the sprayed particles 02, a gap is formed. That is to say, there is an exhaust path, so that when the copper and aluminum foil is being wound, gas can be discharged as quickly as possible, greatly reducing the phenomenon of wrinkling and bubbling in copper and aluminum winding. Compared to the case without providing sprayed particles 02, the copper and aluminum foil does not closely adhere the rotary barrel 01, such that the friction between the copper and aluminum foil and the flat rough surface formed by sprayed particles 02 on the surface of the rotary barrel 01 is increased, which can prevent the copper and aluminum foil from sliding on the rotary barrel 01 after being formed into a roll.

(17) In using the present disclosure:

(18) In use, a suitable diameter of sprayed particles 02 is first selected in accordance with the thickness of copper and aluminum foil to be wound; and a reinforcement agent and sprayed particles 02 are then together applied to the rotary barrel 01.

(19) If the thickness of the copper and aluminum foil to be wound is below 6 ym, the diameter range of sprayed particles 02 is chosen to be 2-8 ym. In this case, copper and aluminum foil can be well attached on the rotary barrel 01, and when copper and aluminum foil is stored in a roll, this enables facilitating copper and aluminum foil smoothing and flattening, and helps to start up the copper and aluminum foil winding.

(20) If the thickness of the copper and aluminum foil to be wound is above 6 ym, the diameter range of sprayed particles 02 is chosen to be 9-15 ym. In this case, copper and aluminum foil is attached on the rotary barrel 01, and also, an exhaust path is formed as a result of the gap between the sprayed particles 02, so that when copper and aluminum foil is being wound, gas can be discharged as quickly as possible, greatly reducing the phenomenon of wrinkling and bubbling in copper and aluminum foil winding.

(21) The above are only the embodiments of the present disclosure and are not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various alterations and variations. Any modifications, equivalent substitutions, and improvements etc. made within the spirit and principle of the present disclosure shall fall within the scope of claims of the present disclosure.
