Description

Technical Field

[0001] The invention relates to the technical field related to electrolytic copper foil, in particular to an insulating device for a cathode roller driving assembly of a foil production machine. Background Art

[0002] The raw foil machine is mainly composed of a tank body, a cathode roller drive device, an anode plate, a lithium copper foil processing device, a winding device, a polishing device, and a cathode roller. It is essentially an electrolytic device. When the raw foil machine is running, the cathode roller rotates continuously, and its electrolytic current is generally above 20,000A, and can even reach about 50,000A. Under the condition of large current, the insulation device in the cathode roller drive assembly is crucial. By achieving effective isolation between the cathode current, the anode current and the ground, the internal insulation requirements of the cathode roller of the drive assembly can be effectively achieved to ensure the production and operation of the copper foil, so as to avoid the hidden danger of "electrical burnout" of the equipment in the production of copper foil. Specifically, the insulating partition is set at the non-critical point of the mechanical structure to ensure that the partition requirements are met and the accuracy of the equipment is used. Most of them use insulating and corrosion-resistant materials and sleeves, and generally choose multiple insulation methods. To this end, we propose a new type of insulation device for the cathode roller drive assembly of the raw foil machine.

[0003] The utility model patent with the authorization announcement number CN208762589U discloses an insulation device for cathode roller drive. This device only insulates the drive gear, but does not insulate the drive motor and the meshing of the two gears. Once the insulation of the drive gear fails, it will directly cause electric shock to the cathode roller, resulting in significant economic losses. This utility model patent designs three layers of insulation protection for the entire cathode roller drive device, fundamentally avoiding the risk of single-layer insulation failure and greatly improving the safety performance of the equipment during production and operation. Summary of the invention

[0004] In order to overcome the deficiency of the safety risk caused by the insulation failure of the cathode roller driving device in the prior art, the present invention proposes an insulation device of the cathode roller driving assembly.

[0005] The present invention comprises a driving motor, a driving insulating sleeve, a coupling, an insulating baffle and an insulating plate. The driving motor is mounted on the insulating plate and fixedly connected to the coupling through a coupling. The insulating baffle is fixed on the bottom surface of the insulating sleeve installation groove of the outer end surface of the coupling. The driving insulating sleeve is fixed in the insulating sleeve installation groove.

[0006] The outer surface of the driving insulating sleeve is fixedly connected to the inner surface of the insulating sleeve mounting groove via a key.

[0007] The end faces of the coupling and the mating end of the coupling are provided with through screw mounting holes, and the insulating baffle is fixedly connected to the coupling by a first screw; an insulating sleeve mounting groove is provided on the other end face of the coupling; the inner diameter of the insulating sleeve mounting groove is the same as the outer diameter of the driving insulating sleeve.

[0008] A small insulating sleeve is mounted on the first screw.

[0009] At the connection between the coupling and the drive motor, the motor insulation sleeve is sleeved on the drive motor shaft, the insulation plate is located on the end surface of the drive motor shaft, and the inner end surface of the insulation plate is closely fitted with the end surfaces of the motor insulation sleeve and the spacer sleeve; the blocking plate is fixedly connected to the insulation plate to ensure insulation between the drive motor and the coupling. The spacer sleeve is sleeved on the outer circumferential surface of the motor insulation sleeve.

[0010] The coupling is sleeved on the outer circumferential surface of the motor insulating sleeve, and the inner end surface of the coupling is fitted with the positioning surface on the motor insulating sleeve, and the outer end surface is fitted with the inner end surface of the spacer sleeve.

[0012] The object of the present invention is to provide an insulating device for a cathode roller driving assembly of a foil machine to prevent a short circuit from occurring during the process of driving the cathode roller of the foil machine to rotate the foil.

[0013] In the present invention, the motor insulating sleeve and the insulating plate constitute a layer of insulation protection for the motor, the large insulating sleeve and the insulating block constitute a layer of insulation protection inside the coupling assembly, and the driving insulating sleeve and the insulating baffle constitute a layer of insulation protection at the end of the coupling when the cathode roller is driven to rotate. These three layers of insulation protection constitute the insulation device of the cathode roller driving assembly.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Different from the prior art, the present invention provides an insulation device for a cathode roller drive assembly. Specifically, an insulation partition is set at a non-critical point of the mechanical structure, a motor insulation sleeve and an insulation plate are set between the drive motor and the coupling, a large insulation sleeve and an insulation block are set inside the coupling assembly, and a drive insulation sleeve and an insulation baffle are set at the contact point between the coupling and the cathode roller shaft. The design of the three insulation structures avoids the safety problem caused by the failure of a single layer of insulation, greatly reduces the risk of insulation failure of the cathode roller drive device at the technical level, and ensures the safety of the production process.
