[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0020] This utility model provides a clamp for a cathode roller, the structure of which is as follows: Figure 1 - Figure 4 As shown, it includes a foil-making machine 1, a cathode roller 2, a bearing 3, a bottom hoop 4, an adjusting mechanism 5, a top hoop 6, and a fixing mechanism 7.

[0021] The cathode roller 2 includes a roller body 21 and a main shaft 22, with the main shaft 22 passing through the middle of the roller body 21.

[0022] The main shaft 22 is fixedly connected to the inner ring 31 of the bearing 3.

[0023] The bottom hoop 4 is hinged to the foil-making machine 1 in the middle.

[0024] The fixed end of the adjustment mechanism 5 is connected to the foil-making machine 1, and the movable end of the adjustment mechanism 5 is connected to the bottom hoop 4. The adjustment mechanism 5 is used to adjust the levelness of the bottom hoop 4.

[0025] The top hoop 6 is connected to the bottom hoop 4, and the outer ring 32 of the bearing 3 is connected between the bottom hoop 4 and the top hoop 6.

[0026] The fixing mechanism 7 is used to fix the bottom hoop 4 and the top hoop 6 together.

[0027] During use, after the device is installed, the initial levelness is determined, and the adjustment mechanism 5 is activated. During the adjustment process, the level instrument 52 is used for auxiliary detection. After leveling is completed, the adjustment mechanism 5 locks the current position to prevent displacement during operation. The outer ring 32 of the bearing 3 is embedded into the arc-shaped groove of the bottom hoop 4, ensuring that the outer ring 32 fits against the inner wall of the bottom hoop 4. The top hoop 6 is then placed on top, making the inner wall of the top hoop 6 in close contact with the top of the outer ring 32 of the bearing 3, forming a full-circumferential wrapping fixation of the outer ring 32 of the bearing 3. The top hoop 6 and the bottom hoop 4 are locked by the fixing mechanism 7. After the outer ring 32 of the bearing 3 is fixed by the top and bottom hoop 4, its axis remains coaxial with the leveled bottom hoop 4, thereby driving the inner ring 31 of the bearing 3 and the main shaft 22 to maintain a level position synchronously, and ensuring the levelness of the axis of the cathode roller 2 body 21.

[0028] In this invention, the adjustment mechanism 5 can effectively compensate for the levelness defects caused by manufacturing errors and wear of the fixed seat, ensure the levelness of the axis of the main shaft 22 of the cathode roller 2, control the radial runout and axial movement of the cathode roller 2 during operation, and improve production quality.

[0029] To adjust the levelness of the bottom hoop 4, please refer to... Figure 3 In a preferred embodiment, the adjusting mechanism 5 includes two screws 51, both of which are threadedly connected to the foil-making machine 1. The two screws 51 are arranged at intervals along the axial direction of the main shaft 22, and the ends of the two screws 51 respectively abut against the bottom sides of the bottom hoop 4.

[0030] During use, the tilt direction is determined by observing the level 52 at the top of the base hoop 4. If the left side of the base hoop 4 is too low, rotate the left screw 51 clockwise, causing the screw 51 to move upward along the fixing nut 53, pushing against the bottom left side of the base hoop 4, causing the base hoop 4 to swing counterclockwise around the hinge axis, gradually increasing the height of the left side. If the right side of the base hoop 4 is too low, rotate the right screw 51 clockwise, causing the screw 51 to move upward and push against the bottom right side of the base hoop 4, causing the base hoop 4 to swing clockwise around the hinge axis, gradually increasing the height of the right side.

[0031] To facilitate observation of the levelness of the bottom hoop 4 and improve inspection accuracy, please refer to... Figure 3 In a preferred embodiment, the adjusting mechanism 5 further includes a level 52, which is embedded in the bottom hoop 4.

[0032] When in use, the traditional design without a level 52 requires external auxiliary tools for detection, which results in measurement errors and cumbersome operation. Inaccurate detection can easily lead to leveling deviations. The level 52 is embedded in the base hoop 4 and is subjected to force and reflects the level status synchronously with the base hoop 4. It can capture minute level deviations in real time, improving the accuracy of deviation recognition.

[0033] To improve the stability of screw 51, please refer to... Figure 3In a preferred embodiment, the adjusting mechanism 5 further includes a nut 53, which is threaded onto the screw 51 and abuts against the foil-making machine 1.

[0034] When in use, after the levelness calibration is completed, keep the screw 51 stationary and rotate the nut 53 corresponding to the screw 51 clockwise to move it upward and tightly press it against the bottom surface of the foil making machine 1 frame. Utilize the friction between the nut 53 and the frame, the nut 53 and the screw 51, and the self-locking characteristics of the thread to fix the axial position of the screw 51 and prevent vibration from causing the screw 51 to loosen.

[0035] To further improve the stability of screw 51, please refer to... Figure 3 In a preferred embodiment, the adjusting mechanism 5 further includes a butterfly spring 54, which is sleeved on the screw 51 and located between the nut 53 and the foil-making machine 1. The two ends of the butterfly spring 54 abut against the nut 53 and the foil-making machine 1, respectively.

[0036] In use, the traditional design without a butterfly spring 54 relies solely on the self-locking of the nut 53 thread and frictional locking. High-frequency vibrations during the operation of the foil-making machine 1 can easily lead to increased thread clearance and slight loosening. With the butterfly spring 54 installed, it is compressed when the nut 53 is tightened, generating a continuous elastic preload. This elastic force always acts between the nut 53 and the frame, forming dynamic pressure compensation. When equipment vibration causes the thread to loosen, the elastic restoring force of the butterfly spring 54 can immediately fill the thread clearance, suppress nut 53 displacement, and reduce the possibility of screw 51 shifting or moving.

[0037] To improve leveling accuracy, please refer to... Figure 3 In a preferred embodiment, the adjusting mechanism 5 further includes a top block 55, which is connected to the end of the screw 51 and abuts against the bottom hoop 4.

[0038] When in use, when the end of the traditional screw 51 directly abuts against the bottom hoop 4, it is easy to slip due to the offset of the contact point and the smooth surface, which affects the leveling accuracy. The top of the top block 55 is designed to fit the bottom of the bottom hoop 4. When abutting, it can automatically center itself, ensuring that the pushing force of the screw 51 is transmitted along the normal direction of the bottom hoop 4 without lateral force interference.

[0039] To reduce wear between the top block 55 and the screw 51, please refer to... Figure 3 In a preferred embodiment, the top block 55 is rotatably connected to the end of the screw 51.

[0040] In use, the friction between the traditional fixed top block 55 and the bottom hoop 4 is sliding friction, which results in a large amount of wear. The rotating top block 55 rotates through the ball head, which transforms the friction into rotational friction. This reduces frictional resistance, decreases the wear of the top block 55, and extends its service life.

[0041] To secure the top hoop 6 to the bottom hoop 4, please refer to... Figure 2 In a preferred embodiment, the fixing mechanism 7 includes two bolts 71, both of which are inserted through the top hoop 6 and both of which are threaded onto the bottom hoop 4.

[0042] In use, the two bolts 71 of the fixing mechanism 7 are symmetrically inserted radially along the main shaft 22 into the preset through holes of the top hoop 6, and precisely engage with the threaded holes of the bottom hoop 4 at corresponding positions. The inner walls of the top hoop 6 and the bottom hoop 4 are provided with arc-shaped grooves to wrap around the outer ring 32 of the bearing 3. When the adjusting mechanism 5 has completed the leveling calibration of the bottom hoop 4, the outer ring 32 of the bearing 3 is placed in the arc-shaped groove of the bottom hoop 4, the top hoop 6 covers the top of the outer ring 32 of the bearing 3, and the two bolts 71 are screwed into the threaded holes of the bottom hoop 4, thus fixing the top hoop 6 and the bottom hoop 4 together.

[0043] To facilitate alignment of the top hoop 6 and the bottom hoop 4, please refer to... Figure 3 In a preferred embodiment, the fixing mechanism 7 further includes a positioning protrusion 72 and a positioning clamping block 73. The positioning protrusion 72 is connected to the top hoop 6, and the positioning clamping block 73 is connected to the bottom hoop 4. The positioning clamping block 73 is used to accommodate the positioning protrusion 72.

[0044] When in use, the trapezoidal guide surface of the positioning protrusion 72 can guide the top hoop 6 to quickly align with the bottom hoop 4 without repeatedly adjusting the position of the bolt 71 hole. The guiding effect is more significant, especially in narrow operating spaces or single-person installation scenarios, reducing the dependence on the operator's skill level and improving installation efficiency.

[0045] To reduce the possibility of bolt 71 loosening, please refer to... Figure 2 In a preferred embodiment, the fixing mechanism 7 further includes an anti-loosening tooth block 74 and an anti-loosening tooth ring 75. The anti-loosening tooth ring 75 is sleeved on the nut of the bolt 71. The top clamp 6 is provided with a groove 76. The anti-loosening tooth block 74 is engaged in the groove 76. The anti-loosening tooth block 74 and the anti-loosening tooth ring 75 are engaged.

[0046] When in use, after tightening the bolt 71, push the anti-loosening tooth block 74 along the slot 76 so that the serrations of the anti-loosening tooth block 74 are fully engaged with the serrations of the anti-loosening tooth ring 75. At this time, the locking part of the anti-loosening tooth block 74 is tightly fitted with the slot 76, restricting the anti-loosening tooth block 74 from moving radially. After engagement, the anti-loosening tooth ring 75 is locked by the anti-loosening tooth block 74 and cannot rotate around the axis of the bolt 71, thereby restricting the reverse loosening of the bolt 71 and forming a mechanical anti-loosening closed loop.

[0047] To better understand this utility model, the following is combined with... Figure 1 - Figure 4 The working principle of a clamp for a cathode roller 2 according to the present invention is described in detail below: After the device is installed, the initial levelness is determined, and the adjustment mechanism 5 is started. During the adjustment process, the level 52 is used for auxiliary detection. After leveling is completed, the adjustment mechanism 5 locks the current position to prevent displacement during operation. The outer ring 32 of the bearing 3 is embedded into the arc-shaped groove of the bottom clamp 4 to ensure that the outer ring 32 fits against the inner wall of the bottom clamp 4. The top clamp 6 is then placed on top, so that the inner wall of the top clamp 6 is in close contact with the top of the outer ring 32 of the bearing 3, forming a full-circumferential wrapping fixation of the outer ring 32 of the bearing 3. The top clamp 6 and the bottom clamp 4 are locked by the fixing mechanism 7. After the outer ring 32 of the bearing 3 is fixed by the top and bottom clamps 4, its axis remains coaxial with the leveled bottom clamp 4, thereby driving the inner ring 31 of the bearing 3 and the main shaft 22 to maintain horizontality synchronously, and ensuring the horizontality of the axis of the cathode roller 2 body 21.

[0048] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
