FIG. 2 is a schematic bottom view of the present utility model;
FIG. 3 is a cross-sectional view of a twin-screw shaft;
FIG. 4 is a schematic view of a cutting mechanism according to the present utility model.
Detailed Description
Referring to fig. 1, fig. 2, fig. 3 and fig. 4, a semi-solid battery slurry pressing and forming device comprises a screw discharging machine 1, wherein a discharging hole of the screw discharging machine 1 is connected with an inlet of a discharging die 2, and a battery box 3 and a cutting mechanism 4 are arranged at an outlet of the discharging die 2.
The screw rod discharger 1 includes discharger casing 5 and installs the screw rod axle 6 in discharger casing 5, and discharger casing 5 one end is provided with reducing gear box 7 and motor 8, the other end is the discharge gate, and the feed inlet is offered at discharger casing 5 top near reducing gear box 7 one end, and feed inlet department installs feeder hopper 9, and reducing gear box 7, the other end is unsettled is connected to screw rod axle 6 one end for discharge gate department does not stop, can let battery slurry send out smoothly.
The screw discharging machine 1 specifically adopts a double screw structure, the rotation directions of the two screw shafts 6 are opposite, the spiral blades 11 on the two screw shafts 6 are tangential and staggered, and extremely low shear stress is generated without damaging the slurry performance while ensuring the forward conveying and inward extrusion functions.
The cutting mechanism 4 comprises a pin shaft 12, a sleeve 13 is movably sleeved on the pin shaft 12, a support 14 is fixed on the sleeve 13, a cutting metal wire 15 is fixed on the support 14, the cutting metal wire 15 is arranged between the battery box 3 and the discharging die 2, the length of the cutting metal wire 15 is larger than the size of the battery box 3, the support 14 can rotate in sequence, the support 14 cannot interfere with the battery box 3 and the discharging die 2 when slurry switching is completed, and a handle 10 is arranged outside the support 14 for facilitating cutting.
The working principle is as follows: the battery slurry is sent into the screw rod discharging machine 1 from the feeding hopper 9, the twin screw rod synchronously rotates in different directions, the slurry is forwards conveyed and generates extrusion force, the slurry can be extruded into a shape corresponding to an inner cavity of the discharging mold 2, a cylinder and a cuboid are common, the embodiment is a flat rectangle, the battery slurry is formed into a brick-shaped cuboid when passing through the discharging mold 2, and then is sent into the battery box 3, when the battery box 3 is filled, the bracket 14 is rotated, the cutting wire 15 cuts the originally continuous battery slurry, the filled battery box 3 is taken out, the empty battery box 3 is placed into a discharging hole, the battery slurry cut originally in the discharging mold 2 is continuously discharged into the battery box 3, and continuous production can be realized by repeatedly cutting and removing the full battery box and replacing the empty battery box. Since the battery paste is not liquid, the cutting wire 15 is thin, leaving a small gap between the battery case 3 and the discharge die 2 does not cause leakage of the paste.
