Abstract
The utility model discloses a rolling compound machine of electrodes of a lithium battery. The rolling compound machine comprises a housing, 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 an extension spring and/or a compression spring; one end of the pressure spring is positioned on the upper rolling shaft through a shaft sleeve; and the other end of the pressure spring is fixed on the housing below or above the upper rolling shaft. The rolling compound machine uses the spring to replace a hot-pressing cylinder and a motor to serve as a pressure control piece, so that the energy is saved; and the spring can be used for automatically adjusting the degree of the pressure according to changes of a clearance between the upper rolling shaft and the lower rolling shaft, so that for the production of the electrodes with millimeter level thicknesses or centimeter lever thicknesses, the pressure produced by the rolling compound machine can satisfy corresponding production requirements.
Description
Technical field
The utility model relates to a kind of roller press, is specifically 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).
Background technology
But lithium battery is a kind of specific energy height of current development in the world, pollution-free, in light weight, high security, shape arbitrariness, memoryless property, long-life novel secondary energy sources, 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 being combined into, extruding has certain thickness electrode of lithium cell. stable for the thickness of electrode that guarantees to generate, need between upper and lower seaming roll, apply pressure stable.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.
The utility model content
The technical problems to be solved in the utility model provides 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 utility model 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, last roll extrusion group comprises seaming roll, goes up rolling shaft, goes up the roll extrusion pedestal, following roll extrusion group comprises seaming roll, following rolling shaft, following roll extrusion pedestal, power motor down, two groups of seaming rolls all are fixed on the corresponding rolling shaft, and rolling shaft is installed on the corresponding roll extrusion pedestal; Last roll extrusion group also comprises the compression spring that last rolling shaft is applied downforce, and compression spring lays respectively at the rolling shaft both sides, and an end of each lateral pressure spring all is positioned on the rolling shaft by axle sleeve, and the other end of compression spring is fixed on the casing.
Further, be provided with the gear pair that is used for transmission between the 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 the compression spring, and compression spring is an extension spring, and the other end of described compression spring is fixed on the casing below the rolling shaft; Compression spring is the compression spring, and the other end of described compression spring is fixed on the casing of rolling shaft top.
Adopt the technical solution of the utility model, following technique effect is arranged: need not to adjust gearratio between the 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 makes things convenient for the installation of compression spring to connect; The compression spring that promptly 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 in gap between the upper and lower seaming roll, for the production of millimeter and Centimeter Level thickness electrode, the pressure that the utility model produced satisfies corresponding production requirement.
Description of drawings
Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
As shown in Figure 1, the roll extrusion compounding machine of the utility model electrode of lithium cell comprises that casing 1 is with last, following roll extrusion group, last roll extrusion group comprises seaming roll 2, last rolling shaft 3, last pedestal 4, last rolling shaft 3 is applied the compression spring of downforce, following roll extrusion group comprises seaming roll down, following rolling shaft, following roll extrusion pedestal 6, power motor 7, two groups of seaming rolls all are fixed on the corresponding rolling shaft, rolling shaft is installed on the corresponding roll extrusion pedestal, power motor 7 is by rolling shaft under belt 8 transmissions, compression spring comprises extension spring 51 and compression spring 52, compression spring lays respectively at rolling shaft 3 both sides, and an end of each lateral pressure spring all is positioned on the rolling shaft 3 by axle sleeve 9.
The right atrial pressure spring is an extension spring 51, and the other end of compression spring is fixed on the casing 1 of rolling shaft 3 belows; The left side compression spring is compression spring 52, and the other end of compression spring is fixed on the casing 1 of rolling shaft 3 tops.
Be provided with the gear pair 10 that is used for transmission between the upper and lower rolling shaft.
Described axle sleeve 9 is provided with and the direct-connected connecting rod 11 of compression spring, and casing 1 is provided with and the direct-connected hanger 12 of compression spring.
For a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement, type difference as the utility model both sides spring, can certainly be all with extension spring 51 or compression spring 52, the position of corresponding compression spring also can change to some extent; These also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
