[0040] The following describes in detail the various embodiments of the present application in conjunction with the accompanying drawings.

[0041] Please also read Figure 1 and Figure 2The present embodiment provides a rolling device, including a rolling assembly 11, a driving assembly 12 and a dust collecting member 13. The rolling assembly 11 includes a support frame 111, an active pressure roller 112 and a driven pressure roller 114 arranged opposite to each other. The active pressure roller 112 and the driven pressure roller 114 are rotatably connected to the support frame 111 and are used for rolling the material 20 passing between the active pressure roller 112 and the driven pressure roller 114. The driving assembly 12 is connected to the support frame 111, the active pressure roller 112 and the driven pressure roller 114, and is used to drive the active pressure roller 112 and the driven pressure roller 114 to rotate in the opposite direction. When dust is collected on one side of the material 20, a first dust collecting hole 13 is provided on the outer peripheral surface of the active pressure roller 112. 13, the dust collecting member 13 is connected to the first dust collecting hole 113 and is used to absorb the dust generated during the rolling process of the material 20; when the other side of the material 20 is dusted, the outer circumference of the driven pressure roller 114 is provided with a second dust collecting hole 115, and the dust collecting member 13 is connected to the second dust collecting hole 115 and is used to absorb the dust generated during the rolling process of the material 20; when both sides of the material 20 are dusted at the same time, the outer circumference of the active pressure roller 112 is provided with a first dust collecting hole 113, and the outer circumference of the driven pressure roller 114 is provided with a second dust collecting hole 115, and the dust collecting member 13 is connected to the first dust collecting hole 113 and the second dust collecting hole 115 and is used to absorb the dust generated during the rolling process of the material 20. Exemplarily, the material 20 can be a battery tab, and the dust collecting member 13 can be a vacuum cleaner.

[0042] In the above-mentioned rolling device, one end of the material 20 after laser cutting is first extended to between the active pressure roller 112 and the driven pressure roller 114, and then the active pressure roller 112 and the driven pressure roller 114 are driven by the driving component 12 to rotate in the opposite direction, so as to roll the material 20 from a wrinkled state to a flat state, and the dust suction member 13 is started during the rolling process, and the dust suction member 13 absorbs the metal dust generated by the material 20 during the rolling process through the first dust suction hole 113 or the second dust suction hole 115 or the first dust suction hole 113 and the second dust suction hole 115; in this way, by arranging the first dust suction hole 113 on the outer circumferential surface of the active pressure roller 112 and / or the second dust suction hole 115 on the outer circumferential surface of the driven pressure roller 114, that is, the dust suction structure and the rolling component 11 are designed as an integrated whole, so that the distance between the dust suction port and the material 20 in the rolling processing state is closer, so that the dust suction member 13 can suck away the metal dust in time with greater suction force, thereby improving the dust removal effect of the rolling device.

[0043] Please also read Figure 1 and Figure 2In some embodiments, the first dust suction hole 113 includes a first dust suction chamber 1131 and multiple first dust suction ports 1132, each of the first dust suction ports 1132 is connected to the first dust suction chamber 1131, the active pressure roller 112 includes an active shaft 1121 and an active roller 1122, the active shaft 1121 is rotatably connected to the support frame 111 and is provided with a first dust suction chamber 1131, the first dust suction chamber 1131 extends along the axial direction of the active shaft 1121 and is connected to the dust suction member 13, specifically, the dust suction pipe of the dust suction member 13 is connected to one end of the active shaft 1121 through a pneumatic rotary joint to achieve a rotatable sealed connection between the first dust suction chamber 1131 and the connecting pipe, the active roller 1122 is sleeved on the active shaft 1121 and is used to roll one side of the material 20, and multiple first dust suction ports 1132 are evenly distributed on the outer circumferential surface of the active roller 1122.

[0044] In this way, when the active roller 1122 rolls one side of the material 20 and produces metal powder, negative pressure is generated by the dust collecting piece 13, so that the metal dust enters the first dust collecting chamber 1131 through the first dust collecting port 1132, and finally enters the dust collecting piece 13, so that the metal dust can be sucked away in time. At the same time, by setting the first dust collecting port 1132 on the active roller 1122 used for rolling the material 20, the first dust collecting port 1132 is closer to the position where the metal dust is generated, so that the dust collecting piece 13 can quickly suck away the metal dust with greater suction force, thereby achieving a better dust collection effect.

[0045] See also Figure 3 In some embodiments, a first embossing protrusion 1123 is further provided on the outer circumferential surface of the active roller 1122. The first embossing protrusion 1123 is used to emboss one side of the material 20 into a preset shape. The first embossing protrusion 1123 is provided on the outer circumferential surface of the active roller 1122, so as to facilitate the embossing process on one side of the material 20; specifically, the first embossing protrusion 1123 is a plurality of circular protrusions, and the cross-section of the circular protrusion is a circular structure, so as to emboss a circular groove on one side of the material 20. The plurality of circular protrusions protrude and are evenly distributed on the outer circumferential surface of the active roller 1122, and the plurality of circular protrusions and the plurality of first dust suction ports 1132 are arranged at intervals.

[0046] Please also read Figure 1 and Figure 2In some embodiments, the second dust suction hole 115 includes a second dust suction chamber 1151 and a plurality of second dust suction ports 1152. The driven pressure roller 114 includes a driven shaft 1141 and a driven roller 1142. The driven shaft 1141 is rotatably connected to the support frame 111 and is provided with a second dust suction chamber 1151. The second dust suction chamber 1151 extends along the axial direction of the driven shaft 1141 and is connected to the dust suction member 13. Specifically, the dust suction pipe of the dust suction member 13 is connected to one end of the driven shaft 1141 through a pneumatic rotary joint to achieve a rotatable sealed connection between the second dust suction chamber and the connecting pipe. The driven roller 1142 is sleeved on the driven shaft 1141 and is used to roll the other side of the material 20. A plurality of second dust suction ports 1152 are evenly distributed on the outer circumferential surface of the driven roller 1142.

[0047] In this way, when the driven roller 1142 rolls the other side of the material 20 and produces metal powder, negative pressure is generated by the dust collecting piece 13, so that the metal dust enters the second dust collecting chamber 1151 through the second dust collecting port 1152, and finally enters the dust collecting piece 13, thereby completing the dust collection operation. At the same time, by setting the second dust collecting port 1152 on the active roller 1122 used for rolling the material 20, the second dust collecting port 1152 is closer to the position where the metal dust is generated, so that the dust collecting piece 13 can quickly suck away the metal dust with greater suction force, thereby achieving a better dust collection effect.

[0048] See also Figure 4 In some embodiments, a second embossing protrusion 1143 is further provided on the outer circumferential surface of the driven roller 1142. The second embossing protrusion 1143 is used to emboss the other side of the material 20 into a preset shape. By providing the second embossing protrusion 1143 on the outer circumferential surface of the driven roller 1142, it is convenient to perform embossing processing on the other side of the material 20; specifically, the second embossing protrusion 1143 is a plurality of circular protrusions, and the cross-section of the circular protrusion is a circular structure, so as to emboss a circular groove on one side of the material 20. The plurality of circular protrusions protrude and are evenly distributed on the outer circumferential surface of the driven roller 1142, and the plurality of circular protrusions are spaced apart from the plurality of second dust suction ports 1152.

[0049] See also Figure 5 In some embodiments, the driving assembly 12 includes a driving gear 121, a driven gear 122 and a driving member 123. The driving gear 121 is connected to one end of the driving roller 112, the driven gear 122 is connected to one end of the driven roller 114 and meshes with the driving gear 121, and the driving member 123 is connected to the driving gear 121 and the support frame 111. The driving member 123 is used to drive the driving gear 121 to rotate. The driving gear 121 and the driven gear 122 are gears of the same specifications. The exemplary driving member 123 can be a motor, or a rotary cylinder or a rotary hydraulic cylinder.

[0050] In this way, the driving gear 121 is driven to rotate by the driving member 123, and the driving gear 121 drives the active pressure roller 112 to rotate, and drives the driven gear 122 to rotate in the opposite direction, so that the driven pressure roller 114 rotates in the opposite direction with the driven gear 122, so that the active pressure roller 112 and the active pressure roller 112 rotate in the opposite direction to perform rolling processing on the material 20; and the driving gear 121 and the driven gear 122 have the same size specifications, so that the rotation speeds of the active pressure roller 112 and the driven pressure roller 114 remain consistent.

[0051] See also Figure 1 In some embodiments, the rolling device also includes a feeding assembly adjacent to the rolling assembly 11, and the feeding assembly is used to hold the material 20 and feed the rolling assembly 11; specifically, the rolling assembly 11 includes a rotating drum and two baffles, and the material 20 is wrapped around the outer periphery of the rotating drum. The two baffles are arranged at both ends of the rotating drum and are used to stop the material 20 wrapped around the outer periphery of the rotating drum, so that the material 20 can be more neatly wrapped around the outer periphery of the rotating drum, and provide feeding power under the continuous rolling pressure of the active pressure roller 112 and the driven pressure roller 114, thereby realizing automatic continuous feeding.

[0052] The working principle of the above-mentioned roller pressing device is roughly as follows:

[0053] The driving gear 121 is driven to rotate by the driving member 123, and the driving gear 121 drives the driven gear 122 to rotate in the opposite direction and drives the driving roller 112 to rotate synchronously, and the driven roller 114 rotates in the opposite direction along with the driven gear 122, thereby achieving synchronous reverse rotation of the driving roller 112 and the driven roller 114;

[0054] The active pressing roller 112 performs a rolling process on one side of the material 20, and the passive pressing roller 114 performs a rolling process on the other side of the material 20, thereby achieving rolling process on both sides of the material 20 at the same time;

[0055] During the rolling process, the dust suction piece 13 simultaneously suctions the metal dust generated on both sides of the material 20 during the rolling process through the first dust suction hole 113 and the second dust suction hole 115, so as to promptly suck away the metal dust generated during the rolling process of the material 20, thereby realizing the synchronous operation of dust removal and rolling process.

[0056] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure.
