[0023] The technical solution of the utility model is further described in detail below through embodiments and in combination with the accompanying drawings, but the utility model is not limited to the following embodiments.

[0024] The step roller is a special tool for smoothing the pole piece during the production process of the pole piece material 7. The magnet inside the step roller can also remove impurities such as iron filings from the pole piece material 7. There are also restrictions such as copper and zinc prohibition during the production process of the pole piece material 7. Therefore, each component in the pole piece production process has strict requirements on the materials used. In recent years, the country has vigorously developed the new energy industry, and lithium batteries have also developed rapidly. As an important component of lithium batteries, pole piece materials 7 directly affect the performance of lithium batteries.

[0025] However, the step roller is relatively small in size and long in length, which makes it extremely difficult to install the internal parts. During the installation process, it was found that the magnet mounting strip 2 was too wide and extremely difficult to install. Due to limited space, after the internal magnet fits the inner surface of the roller, the mounting strip will arch, causing the difficulty of installation at both ends to increase rapidly, and the adsorption effect of the magnet is not particularly good. The existing technology cannot provide special tools, and the defects need to be solved urgently.

[0026] In order to solve the above problems, the present embodiment provides a movable step roller, comprising: a roller, a support body 1 arranged on both sides of the roller, a magnet mounting bar 2 arranged in the roller, and a turntable 3 connecting the magnet mounting bar 2 and the support body 1, wherein the magnet mounting bar 2 can rotate around the axis of the turntable 3, and a groove is arranged on the magnet mounting bar 2;

[0027] The movable step roller also includes an electromagnet 4 embedded in the groove of the magnet mounting strip 2 and a Teflon baffle 5 arranged outside the roller. The Teflon baffle 5 is arranged outside the roller and can move along the axis of the roller.

[0028] In this embodiment, Figure 1 As shown, the roller is used to smooth the pole piece material 7, the electromagnet 4 is used to clean the impurities adhering to the pole piece, the support body 1 can be a structure such as a bracket that can be supported on the ground, and the turntable 3 includes a fixed part and a movable part. The fixed part is arranged on the support body 1, and the movable part is connected to the roller.

[0029] A turntable 3 and a support body 1 are respectively provided on both sides of the roller of this embodiment, and the roller can rotate at a certain height from the ground.

[0030] During the installation and production process of the unit, this structure has a good effect. First, the magnet installation strip 2 will not be arched during installation, and the installation is more convenient; second, the magnet adsorption effect is better, and the cleaning effect of the pole piece material 7 is better.

[0031] The Teflon baffle 5 is made of polytetrafluoroethylene, the English abbreviation of polytetrafluoroethylene is PTFE, and its trademark transliteration name is Teflon.

[0032] This material is resistant to acid, alkali and various organic solvents, and is almost insoluble in all solvents. At the same time, polytetrafluoroethylene is resistant to high temperatures and has an extremely low friction coefficient, so it can be used as a lubricant.

[0033] The Teflon baffle 5 is arranged outside the roller, and the Teflon baffle 5 can move along the axis of the roller, and the step roller can be suitable for pole piece materials 7 of more sizes.

[0034] It may be preferred that a through shaft 6 is further provided on the axis of the roller, and the through shaft 6 serves as the axis of rotation of the roller.

[0035] It is preferred that

[0036] Furthermore, a plurality of magnet mounting bars 2 parallel to each other are arranged in the roller, and the plurality of magnet mounting bars 2 are evenly arranged along the circumferential direction of the rotating disk 3;

[0037] The magnet mounting strip 2 is connected to the turntable 3 by fasteners, and the rotation of the turntable 3 can drive multiple magnet mounting strips 2 to rotate around the axis of the turntable 3 at the same time;

[0038] The corresponding positions of the plurality of magnet mounting strips 2 are all provided with grooves, and the electromagnets 4 inside the roller are embedded in the grooves at the corresponding positions of the magnet mounting strips 2 and are fixedly connected to the magnet mounting strips 2 .

[0039] In this embodiment, Figure 2 As shown, the magnet mounting strip 2 is mainly used to fix the electromagnet 4. The purpose of evenly arranging multiple magnet mounting strips 2 along the circumferential direction of the turntable 3 is to fix and limit the electromagnet 4 through the grooves on the outer side of the magnet mounting strip 2.

[0040] In addition, since the inner diameter of the roller may not match the electromagnet 4 and the magnet mounting strip 2, the step roller, that is, the roller shaft of this embodiment, often needs to be disassembled for maintenance during the production process. The step roller is relatively small in size and long in length, which creates great difficulties for the installation of internal parts. During the installation process, it was found that the magnet mounting strip 2 is too wide and extremely difficult to install. Due to limited space, after the internal magnet fits with the inner surface of the roller, the mounting strip will arch, resulting in a rapid increase in the difficulty of installation at both ends, and the adsorption effect of the magnet is not particularly good.

[0041] The depth of the step can also adapt to the inner diameter of the step roller. After the electromagnet 4 is installed on the magnet mounting bar 2, the outside of the electromagnet 4 is close to the inner surface of the step roller, reducing the difficulty of disassembly and maintenance.

[0042] The movable step roller of this embodiment includes four magnet mounting strips 2, the thickness of the magnet mounting strips 2 is 10 mm, the depth of the groove is 5 mm, and the multiple magnet mounting strips 2 are arranged in a ring shape inside the roller, and the grooves are arranged on the outer surface of the magnet mounting strips 2.

[0043] Preferably, the movable step roller further comprises a Teflon sleeve 8 sleeved on the outside of the roller, the Teflon sleeve 8 is connected to the Teflon baffle, and can move outside the roller along the length direction of the roller.

[0044] Furthermore, a plurality of electromagnets 4 are arranged in the roller, and the plurality of electromagnets 4 are arranged along the length direction of the magnet mounting bar 2. The central part of the electromagnet 4 is connected to the magnet mounting bar 2, and the outer surface of the electromagnet 4 is close to the inner surface of the roller.

[0045] In this embodiment, Figure 1 , Figure 2 As shown, the number of electromagnets 4 can be set according to the length of the roller, and the electromagnets 4 are connected to the magnet mounting bar 2 by detachable fasteners, and the position of the electromagnets 4 on the magnet mounting bar 2 can be adjusted by the fasteners. For pole piece materials 7 with a longer length, multiple electromagnets 4 can be arranged at intervals to increase the effect of removing metal impurities.

[0046] Furthermore, a slide bar 9 is arranged on the outside of the roller, and both ends of the slide bar 9 are connected to the support body 1, and the slide bar 9 is arranged parallel to the roller;

[0047] The Teflon baffle 5 is connected to the slide bar 9 , and the Teflon baffle 5 can move along the length direction of the slide bar 9 .

The Teflon baffle 5 can be connected to the sliding rod 9 through a connecting piece.

[0049] Preferably, the Teflon baffle 5 can also be movably mounted on the roller in other ways, such as being magnetically attracted to the support body 1 or connected through other brackets fixed near the roller.

[0050] Furthermore, the movable step roller also includes a baffle connecting plate 10, which is used to connect the Teflon baffle 5 and the slide rod 9.
