Description

Technical Field

[0001] This utility model relates to the technical field of electrolytic copper foil production equipment, specifically a novel bearing seat device for the rollers of a copper foil production machine. Background Technology

[0002] The foil-forming machine is the core equipment in the production of electrolytic copper foil. It uses a cathode roller that rotates continuously in an electrolyte solution, causing copper ions to be electrodeposited on its surface to form the raw foil. The cathode roller is typically large and heavy, and needs to operate stably at high speeds and high precision. The bearing seats at both ends of the roller are its core supporting components, and their performance directly affects the roller's operational stability, the uniformity of the copper foil quality, and the service life of the equipment.

[0003] Currently, traditional foil-making machine roller bearing housings generally suffer from the following technical defects: 1. Poor sealing: The foil-making machine is located in a harsh environment with high temperature, high humidity, and acidic electrolyte mist. The traditional bearing housing has a simple sealing structure, which is easily invaded by corrosive media, causing the lubricating grease inside the bearing to deteriorate, and corrosion and pitting to occur in the bearing raceway and rolling elements. This leads to increased vibration and noise, and ultimately premature bearing failure, seriously affecting the continuity of production.

[0004] 2. Insufficient self-aligning capability: Due to factors such as installation errors, foundation settlement, or roller self-weight deflection, misalignment can easily occur between the roller shaft and the bearing housing. Traditional bearing housings use ordinary bearings with limited self-aligning capability. Misalignment will generate huge additional loads, leading to uneven bearing wear and abnormal temperature rise. This not only shortens the bearing life but also affects the radial runout accuracy of the roller, resulting in uneven copper foil thickness.

[0005] 3. Poor heat dissipation: Bearings generate a lot of heat when running at high speeds. Traditional bearing housings are mostly solid, thick-walled structures with small heat dissipation areas. Heat accumulation can easily lead to excessively high bearing temperatures, decreased lubricant performance, and a vicious cycle. It can also conduct heat to the rollers, affecting the crystallization quality of the copper foil.

[0006] 4. Inconvenient maintenance: When the bearing needs to be replaced, traditional integral or poorly structured bearing housings require disassembly of the drive motor, coupling, and even part of the rollers, which is complicated, time-consuming, and results in significant downtime losses.

[0007] Therefore, there is an urgent need for a new type of bearing housing device that has strong sealing performance, can automatically adjust itself, has good heat dissipation, and is easy to maintain, in order to improve the overall performance of foil production machines. Utility Model Content

[0012] Preferably, a locking nut is fitted onto the locking sleeve, and the locking nut is threadedly engaged with the locking sleeve; after the locking nut is tightened on the locking sleeve, it abuts against one side of the inner ring of the bearing.

[0013] Preferably, there are two heat dissipation slots; the two heat dissipation slots are symmetrically arranged on both sides of the bearing housing body.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figures 1 to 3 As shown, a novel bearing seat device for use on the rollers of a copper foil forming machine includes: Bearing housing base 1, used for mounting on the equipment frame; The bearing housing body 7 is mounted on the bearing housing base 1; the bearing 6 is installed inside the bearing housing body 7; the outer ring of the bearing 6 is connected to the bearing housing body 7, and the inner ring is provided with a locking component, which is used to fix and connect with the functional roller to be operated; a heat dissipation groove 2 is provided on the outer side of the bearing housing body 7, which extends along the radial direction of the bearing 6 to the outer side of the outer ring of the bearing 6; the depth of the heat dissipation groove 2 allows the outer ring of the bearing 6 in this part to contact the outside air for heat exchange. End cap 3 is fixed to one side of bearing housing body 7 and is used to seal bearing 6 inside bearing housing body 7.

[0027] In this embodiment, a through hole 9 is provided on the bearing housing body 7; a bearing hole 10 is provided on one side of the bearing housing body 7 along the axial direction of the through hole 9, and the bearing 6 is installed in the bearing hole 10; the outer ring of the bearing 6 is fitted with the hole wall of the bearing hole 10; one side of the outer ring of the bearing 6 abuts against the bearing housing body 7 to axially position the bearing 6; and the end cap 3 is fastened to the bearing housing body 7 outside the bearing hole 10.

[0028] In this embodiment, the locking component is a locking sleeve 8; the axial projection shape of the locking sleeve 8 is an isosceles trapezoid; the inner ring of the bearing 6 is fitted onto the locking sleeve 8; the inner side of the inner ring of the bearing 6 is provided with an inclined surface that matches the locking sleeve 8; one end of the functional roller is installed inside the locking sleeve 8, and the axes of the functional roller, the bearing 6 and the locking sleeve 8 coincide.

[0029] In this embodiment, a locking nut 11 is fitted onto the locking sleeve 8, and the locking nut 11 is threadedly engaged with the locking sleeve 8. After the locking nut 11 is tightened on the locking sleeve 8, it abuts against one side of the inner ring of the bearing 6. Specifically, the locking nut 11 is tightened along the axial direction of the locking sleeve 8 toward the bearing 6. Because the outer diameter of the locking sleeve 8 near the locking nut 11 is small and the outer diameter of the other end is large, under the limiting action of the locking sleeve 8, the locking nut 11 and one side of the inner ring of the bearing 6 are tightly fitted, so that the locking nut 11 and the inner ring of the bearing 6 maintain synchronous movement. The required operating functional roller is locked by fitting the roller shaft at the shaft end into the set sleeve, and the roller shaft is locked by the threaded engagement between the locking nut 11 and the set sleeve. The end face of the locking nut 11 axially positions the inner ring of the bearing 6.

[0030] In this embodiment, there are two heat dissipation slots 2; the two heat dissipation slots 2 are symmetrically arranged on both sides of the bearing housing body 7.

[0031] In this embodiment, a lubrication injection hole 5 is provided on the bearing housing body 7; the lubrication injection hole 5 is used to inject lubricating oil into the interior of the bearing housing body 7; an oil injection nozzle 4 is installed on the lubrication injection hole 5.

[0032] In this embodiment, a sealing ring 12 is provided on the end cap 3; the sealing ring 12 is placed between the end cap 3 and the bearing housing body 7; the sealing ring 12 is a corrosion-resistant and wear-resistant polytetrafluoroethylene ring or a fluororubber ring.

[0033] In this embodiment, the end cap 3 is a transparent cap, used to observe the internal lubrication of the bearing housing body 7.

[0034] In this embodiment, the bearing housing base 1 has a long and flat structure; the bearing housing base 1 has a first bolt hole 13 at one end and a positioning groove in the middle; the first bolt hole 13 is used to fix the bearing housing base 1 to the equipment frame with bolts; the lower end of the bearing housing body 7 is installed in the positioning groove; the lower end of the positioning groove has a second bolt hole 14, and the lower end of the bearing housing body 7 has a corresponding screw hole, and the bearing housing body 7 is fixed to the bearing housing base 1 by bolts passing through the second bolt hole 14.

[0035] In this embodiment, bearing 6 is a double-row self-aligning roller bearing.

[0036] Working principle: Installation, positioning, and fixing: The bearing housing base 1 is fixed to the equipment frame through the end bolt holes. The top positioning groove precisely limits the bearing housing body 7, and then the body is fastened to the base through the bolts at the lower end of the positioning groove to ensure overall stable installation. The roller shaft of the functional roller is fitted into the locking sleeve 8 of the inner ring of the bearing 6. The locking sleeve 8 adopts an isosceles trapezoidal structure, which is adapted to the inclined surface of the inner ring of the bearing 6. By tightening the locking nut 11 at the end of the locking sleeve 8, the inner ring of the bearing 6 is axially positioned and the roller shaft is locked, ensuring that the roller shaft, locking sleeve 8 and bearing 6 axis coincide, and achieving reliable fixing of the roller.

[0037] Sealing and protection: The end cap 3 is fastened to one side of the bearing housing body 7, and the polytetrafluoroethylene ring or fluororubber sealing ring 12 between it and the bearing housing body 7 forms a sealing structure, which effectively isolates the high temperature and high humidity acidic electrolyte mist in the foil production machine, prevents corrosive media from entering the interior of the bearing 6, and protects the performance of the lubricating grease and the bearing raceway and rolling elements from damage.

[0038] Automatic self-aligning and stable operation: The roller adopts a double-row self-aligning roller bearing. When the roller is misaligned due to installation error, foundation settlement or self-weight deflection, the bearing 6 can automatically compensate for the deviation, eliminate the additional load, avoid uneven wear and abnormal temperature rise of the bearing 6, ensure that the radial runout of the roller is small at high speed, and ensure the uniformity of copper foil thickness.

[0039] Heat dissipation and lubrication assurance: Symmetrical heat dissipation grooves 2 on both sides of the bearing housing body 7 extend radially along the bearing 6 to the outer ring of the bearing 6, allowing the outer ring of the bearing 6 to directly contact the outside air. This facilitates rapid heat dissipation from the high-speed operation of the bearing 6 through heat exchange, ensuring stable operating temperature and preventing grease failure and component thermal deformation. Simultaneously, lubricating oil can be periodically injected through the lubrication injection hole 5 on the bearing housing body 7, guided to the contact surface of the bearing 6 via the grease nipple 4, forming a stable oil film and reducing operational friction loss.

[0040] Convenient maintenance mechanism: The transparent end cover allows real-time observation of the internal lubrication status, enabling predictive maintenance; when it is necessary to repair or replace bearing 6, there is no need to disassemble the drive motor, coupling and roller, only the end cover needs to be opened to operate, which greatly reduces maintenance workload and downtime.
