Description

Grid leveling device

Technical Field

The invention relates to the technical field of grid weaving and manufacturing, in particular to a grid flattening device.

Background

The grid is an important component of the lead storage battery and is used for coating active substances to realize the charge and discharge functions of the storage battery. The prior grid comprises a mesh drawing grid and a casting grid, wherein the mesh drawing grid is generally woven by a weaving machine, and the formed grid needs to be continuously collected in the process of weaving the grid by the weaving machine. Because the width of a knitting machine can be increased in order to improve the manufacturing efficiency of the grid in a production factory, the grid generally has larger width and is inconvenient to collect and transport.

In order to eliminate the limitation on the grid width and improve the working efficiency, a grid winding device is used at present, and a plurality of grids can be wound simultaneously. In the specific winding process, the two sides of the grid need to be tensioned, and then the grid is longitudinally divided into two pieces from the middle of the grid through a cutting knife. However, in the process of cutting the grid, the action force between the cutting knife and the grid can cause the uneven edge of the cut part of the grid, and when an operator handles the collected grid coil, the operator is easily damaged.

Disclosure of Invention

The invention aims to provide a grid flattening device to solve the problem that the cut edges of a grid are not neat after the grid is cut by an existing cutting knife, and therefore operators are prevented from being injured during operation.

In order to achieve the purpose, the technical scheme of the invention is as follows: a grid leveling device comprises a frame body, a first screw rod and a driving mechanism, wherein the first screw rod is used for fixing a cutting knife, the driving mechanism is used for driving the first screw rod, and the driving mechanism drives the first screw rod to drive a cutting edge of the cutting knife to align to a grid;

at least two fixing mechanisms are arranged on the frame body on the outer side of the first screw rod, and the lower parts of the fixing mechanisms are connected with pressing mechanisms in a sliding manner;

the compressing mechanism comprises a U-shaped frame with an upward opening and a connecting plate in threaded connection with the first screw rod, the connecting plate is fixed on the upper portion of the U-shaped frame, an air cavity forming an inflator structure with the fixing mechanism is arranged on the side wall of the U-shaped frame, and the air cavity is communicated with an air pipe facing the lower portion of the U-shaped frame; the cutting knife penetrates through the lower part of the U-shaped frame, and a button switch electrically connected with the driving mechanism is further arranged at the bottom of the U-shaped frame.

The principle and the beneficial effects of the scheme are as follows: actuating mechanism can drive first screw rod and rotate, and first screw rod can drive the vertical lapse of connecting plate under screw-thread fit to the connecting plate takes the U-shaped frame lapse, and the grid can be supported to the bottom of U-shaped frame, and button switch receives the extrusion of grid and can contract this moment, thereby closes actuating mechanism, and actuating mechanism stall so compresses tightly the upper surface of grid. The grid is through cutting knife in the in-process of transmission, so cut into two, because cutting knife and grid interact's effort can make the grid by the partial perk of cutting, but the U-shaped frame compresses tightly the part by the cutting this moment, so the grid can not the perk by the part of cutting to realize that the grid is by smooth cutting. Compared with the traditional cutting mode, the cut part of the grid is compressed through the U-shaped frame, and the unevenness of grid cutting is avoided.

During the downward sliding process of the U-shaped frame, the air cavity can suck air through the air pipe. After the grid is conveyed away, the button switch is not squeezed by the grid any more, so that a circuit of the driving mechanism is switched on, the driving mechanism is started to drive the first screw to rotate reversely, the U-shaped frame slides upwards, gas in the gas cavity is discharged through the gas pipe, and the discharged gas cleans dust on the grid and cut scraps. Compare with traditional cutting mode, can produce certain sweeps among the grid cutting process, the sweeps can influence the quality of grid, clears up the sweeps in cutting process, avoids the manual work to clear up to improve work efficiency.

Further, the driving mechanism is a servo motor or a stepping motor. Servo motor and step motor rotate according to certain angle for servo motor and step motor pivoted moment of torsion are certain, and it is certain to drive the gliding distance of first screw rod drive U-shaped frame, can make the cutting edge part of cutting knife aim at the grid simultaneously.

Furthermore, the fixing mechanism comprises a fixing rod and a sliding rod fixed on the fixing rod, and the sliding rod extends into the air cavity and is connected with the U-shaped frame in a sliding mode. The fixed rod can prolong the formation of the U-shaped frame, the slide rod is arranged in the air cavity, and the slide rod, the air cavity and the air pipe form a mechanism similar to an inflator, so that the air cavity can suck and discharge air, and dust or waste on the plate grid is cleaned through the air.

Further, the lower part of cutting knife is fixed with the second screw rod that screw direction and first screw rod screw thread opposite direction, and second screw rod outside is provided with pushing down the mechanism, and pushing down the mechanism including compressing tightly frame and fixed plate, the fixed plate is fixed on compressing tightly the frame to fixed plate and second screw rod threaded connection compress tightly the lateral wall of frame and be provided with the wind chamber, and the wind chamber intercommunication has the orientation to compress tightly the tuber pipe on frame upper portion, and sliding connection has the bracing piece of fixing on the support body in the wind chamber. When the first screw rod rotates, the first screw rod can drive the cutting knife to rotate, the cutting knife can drive the second screw rod to rotate, the second screw rod drives the compression frame to slide upwards through the fixing plate, so that the compression frame compresses the lower part of the grid, at the moment, the air cavity sucks air through the air pipe under the action of the supporting rod, and scraps such as dust can be sucked into the air cavity. So not only strengthen the dust removal effect of grid, can also make the upper surface and the lower surface of grid compress tightly simultaneously, improve and compress tightly the effect.

Furthermore, sand paper layers are arranged on the upper portion of the pressing frame and the lower portion of the U-shaped frame. During the grid transfer process, burrs present on the grid may be sanded by sand paper. Meanwhile, the burrs which are ground can be cleaned by the air blown out from the air cavity and the air cavity.

Furthermore, the bottom of the U-shaped frame is provided with a groove, the button switch is positioned in the groove, and the bottom of the button switch is provided with a spring which is abutted against the groove. When the button switch is extruded, the button switch can slide towards the groove, and when the button switch cannot slide under the action of the spring, the button switch can be closed, so that the circuit of the driving mechanism is disconnected, the driving mechanism stops working, and the pressing mechanism can completely clamp the grid to flatten the grid.

Further, a sponge layer is arranged at the bottom of the button switch. The sponge layer is used for protecting the button switch, and the button switch and the grid are prevented from being damaged due to friction.
