Abstract
The invention discloses a rolling combination machine for a lithium battery electrode, which comprises a machine shell, an upper rolling group and a lower rolling group, wherein the upper rolling group comprises an upper rolling roller, an upper rolling shaft, an upper rolling shaft frame and a pressure spring; the pressure spring comprises a stretching spring and/or a compression spring; and one end of the pressure spring is positioned on the upper rolling shaft by a shaft sleeve, and the other end of the pressure spring is fixed on the machine shell below or above the upper rolling shaft. In the rolling combination machine, the spring for replacing a hot-press cylinder and a motor is used as a pressure control piece to save energy, and the spring can regulate the pressure automatically according to the change of a gap between the upper rolling shaft and a lower rolling shaft; and in the production of electrodes with millimeter and centimeter-level thicknesses, the pressure generated by the rolling combination machine meets corresponding production requirements.
Description
Technical field
The present invention relates to a kind of roller press, is a kind of lithium band and copper or aluminium net to be carried out the roll extrusion compounding machine that roll extrusion is compounded to form electrode of lithium cell (negative pole) specifically.
Background technology
But lithium battery is that a kind of specific energy of current development in the world is high, pollution-free, lightweight, high security, shape arbitrariness, memoryless property, long-life novel secondary energy, and it all has great application prospect in the military and civilian field.
As known to the public, the operation principle of lithium battery roller press is together by becoming the upper and lower seaming roll of certain interval with lithium and binding member thereof, thereby extrusion cladding becomes to have certain thickness electrode of lithium cell. stable for the thickness of electrode that guarantees to generate, need to apply stable pressure between upper and lower seaming roll.For addressing the above problem, patent CN2613063 discloses a kind of roller press that steady pressure is provided by hot pressing cylinder or servomotor.Yet for the not high electrode slice production of thickness requirement, the disclosed technical scheme of patent CN2613063 is obviously wanted a lot of unnecessary energy (heat energy or electric energy) of loss.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of roll extrusion compounding machine that steady pressure and energy savings can be provided.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of roll extrusion compounding machine of electrode of lithium cell comprises casing and upper and lower roll extrusion group, upper roll extrusion group comprises seaming roll, upper rolling shaft, upper roll extrusion pedestal, lower roll extrusion group comprises lower seaming roll, lower rolling shaft, lower roll extrusion pedestal, power motor, two groups of seaming rolls all are fixed on corresponding rolling shaft, and rolling shaft is installed on corresponding roll extrusion pedestal; Upper roll extrusion group also comprises the compression spring that upper rolling shaft is applied downforce, and compression spring lays respectively at rolling shaft both sides, and an end of each lateral pressure spring all is positioned on upper rolling shaft by axle sleeve, and the other end of compression spring is fixed on casing.
Further, be provided with gear pair for transmission between upper and lower rolling shaft.
Further, described axle sleeve is provided with and the direct-connected connecting rod of compression spring, and casing is provided with and the direct-connected hanger of compression spring.
Further, described compression spring comprises and stretching and/or Compress Spring, and compression spring is extension spring, and the other end of described compression spring is fixed on the casing of rolling shaft below; Compression spring is Compress Spring, and the other end of described compression spring is fixed on the casing of rolling shaft top.
Adopt technical scheme of the present invention, following technique effect is arranged: need not to adjust gearratio between upper and lower rolling shaft, only need set up a pair of travelling gear and realize the structure of gear pair, can realize the drive connection of Constant Linear Velocity; Setting up connecting rod, hanger facilitates the installation of compression spring to connect; The compression spring that namely produces downforce with force direction downwards replaces hot pressing cylinder and motor, can save the energy, and spring can be according to the size of the variation automatic pressure regulation of upper and lower seaming roll gap, for the production of millimeter and Centimeter Level thickness electrode, the pressure that the present invention produces satisfies corresponding production requirement.
