Description

Technical Field

[0001] The utility model relates to the technical field of conductive film production, in particular to a quick-detachable pulley mechanism and coating equipment. Background Art

[0002] With the rapid development of the global new energy industry, lithium-ion batteries are widely used in energy storage and automobiles due to their high energy density and good cycle performance. However, the frequent occurrence of accidents such as battery fires has made lithium-ion battery safety the most basic demand of battery products, among which internal short circuit of the battery is the most important cause of safety problems. For power batteries, external stress such as collision and extrusion is one of the main causes of battery short circuit fire.

[0003] The new composite copper foil and aluminum foil current collector has a multi-layer composite structure of "polymer substrate intermediate layer + thin conductive metal layer". When a short circuit occurs in the battery, it can provide a large resistance through fusing and insulation to cut off or reduce the short-circuit current in a short time, effectively preventing thermal runaway of the battery and improving battery safety.

[0004] The composite current collector substrate is PET / PP, and the copper and aluminum plating is achieved by the winding coating process. However, the traditional winding coating substrate is thicker (more than 20 microns), the coating thickness is thinner (less than 200nm) and is single-sided coating. During coating, the substrate is relatively less heated, and the film can be formed in one time, and the film surface appearance is better. The composite current collector coating substrate is 6 microns or even thinner 4.5 microns, the coating thickness reaches 1000nm and is double-sided coating.

[0005] In order to improve the coating efficiency, the aluminum composite current collector adopts the evaporation coating process. The substrate is thin, and it expands and contracts during drum plating. It is difficult to use back cooling, and wrinkles are very easy to occur. Therefore, the suspension coating process is used. In order to avoid melting due to evaporation heat, high-speed multiple film formation is adopted. During the coating process, the cooling is lowered by laminating with the cooling main roller. The rotation of the cooling main roller is usually driven by a belt and pulley mechanism. During long-term use, the pulley and belt will wear, resulting in errors in the rotation speed of the main roller, which affects the cooling of the film and thus affects its coating quality.

[0006] When both the pulley and the belt are worn, they need to be replaced. The existing pulley is usually fixedly installed at the end of the main roller. After being worn, the entire main roller needs to be removed and then the pulley is removed. The removal and installation process is complicated and inefficient. Utility Model Content

[0007] In order to overcome the deficiencies of the prior art, the utility model provides a quick-detachable pulley mechanism and coating equipment, which can replace the worn pulley without removing the entire main roller, thereby reducing the disassembly time and facilitating the operation.

[0008] The technical solution adopted by the utility model to solve its technical problems is:

The second inclined surface is set to be inclined downward toward the main roller fixing sleeve, and the second inclined surface contacts the side wall surface of the groove placed on the main roller fixing sleeve.

[0012] As a further improvement of the above technical solution, the connecting piece includes a positioning hole and a positioning cylindrical pin, the positioning hole is arranged on one of the split bodies, the positioning cylindrical pin is arranged on the other split body, and the positioning cylindrical pin is plugged into and matched with the positioning hole.

[0014] As a further improvement of the above technical solution, the main roller fixing sleeve and the mounting flange are integrally formed, and the mounting flange is arranged on the outer periphery of the main shaft fixing sleeve.

[0015] As a further improvement of the above technical solution, a mounting plate is provided on the roller shaft, and the main roller fixing sleeve is detachably connected to the mounting plate via a mounting flange.

When the pulley needs to be replaced, it is only necessary to remove the pulley fixing sleeve, and then separate the two parts of the pulley, and then remove the pulley and the belt connected to the pulley, and then replace the new pulley, so that the entire main roller does not need to be removed, which reduces the time of disassembly and is easy to operate.

Specifically, the pulley assembly 2 includes a pulley fixing sleeve 24, a pulley 23, a main roller fixing sleeve 22 and a mounting flange 21. The pulley fixing sleeve 24, the pulley 23, the main roller fixing sleeve 22 and the mounting flange 21 are sequentially sleeved on the roller shaft 12, and the mounting flange 21 is fixedly installed on the main roller 1. The pulley fixing sleeve 24, the pulley 23 and the main roller fixing sleeve 22 are detachably connected to the mounting flange 21. A first placement groove 221 is provided on the main roller fixing sleeve 22, and a second placement groove 241 is provided on the pulley fixing sleeve 24.
