In above-mentioned patent, battery core adopts belt conveyor conveying, and during belt conveyor feeding, columniform lithium cell easily rolls, and causes malalignment, when pushing in film strips, also needs the position again adjusting lithium cell, affects production efficiency.
Utility model content
For overcoming problems of the prior art, the utility model provides the feeding machanism for the plastic equipment of lithium cell that a kind of structure is simple, be convenient to assembling, this feeding machanism has the sliding channel of conveying lithium cell, sliding channel has be in high-order add material level and be in low level go out material level, lithium cell relies on gravity to roll in sliding channel, and released by cylinder going out material level, marshalling in feeding process, evenly, be beneficial to improving production efficiency.
The concrete technical scheme that the utility model adopts is as follows:
For a feeding machanism for the plastic equipment of lithium cell, comprise base, described base have the sliding channel of conveying lithium cell, the two ends of this sliding channel have respectively be in high-order add material level and be in low level go out material level;
The side going out material level is provided with discharging opening, and opposite side is provided with the cylinder releasing lithium cell;
Add material level and the sliding channel gone out between material level is provided with and limits the lithium cell single stop gear passed through, and be covered in the feeding cover plate above sliding channel.
In the utility model, sliding channel has be in high-order add material level and be in low level go out material level, lithium cell relies on gravity to roll in sliding channel, and do not need independently connecting gear, energy consumption is lower; Stop gear is used for making lithium cell single conveying in sliding channel, proper alignment; And by opening feeding cover plate, the lithium cell in sliding channel is adjusted, or the lithium cell in sliding channel is taken out.
As the improvement of technical scheme, described in add material level corresponding sliding channel wall be provided with the baffle plate increased.
The surrounding adding material level has the baffle plate increased, and forms the feeding chamber adding lithium cell in sliding channel, and lithium cell can be stacked on and add in material level, and the lithium cell promoted in sliding channel glides.
As the improvement of technical scheme, described stop gear comprises the first stop gear and the second stop gear arranged successively, and the first stop gear is positioned at the horizontal segment place of described sliding channel, and the second stop gear is arranged on the downslide section place of sliding channel.
Add the bottom surface that material level has inclination, lithium cell can be made in downslide from adding in material level, and next-door neighbour adds the horizontal segment of material level for slowing down the rolling speed of lithium cell, reduces the collision between battery; The downslide section tilted, for accelerating the slip of battery, makes battery going out in material level arrangement closely; First stop gear and the second stop gear, for keeping, lithium cell is single avoids mutual extruding by horizontal segment and downslide section, causes lithium cell to misplace.
As the improvement of technical scheme, the first described stop gear comprises the erecting frame being fixed on sliding channel top, and the bottom of this erecting frame is equipped with along the axially extended positioning plate of sliding channel; The second described stop gear is the arc being arranged in sliding channel both sides and bending along sliding channel.
Positioning plate and arc have position-limiting action to the lithium cell in sliding channel, keep the single downslide of lithium cell.
As the improvement of technical scheme, described feeding cover plate switching, above sliding channel, is convenient to opening of feeding cover plate.Meanwhile, described in go out material level end be hinged with baffle plate, this baffle plate is connected on sliding channel both sides by hook connecting, and baffle plate goes to level, the battery in sliding channel is skidded off, is convenient to the replacing of battery.
The utility model structure is simple, be convenient to assembling, and there is the sliding channel of conveying lithium cell, sliding channel has be in high-order add material level and be in low level go out material level, lithium cell relies on gravity to roll in sliding channel, and released by cylinder going out material level, marshalling in feeding process, evenly.
