Description

A device for crushing and collecting lithium battery pole pieces

technical field

The utility model relates to the field of lithium battery production, in particular to a lithium battery pole piece slitting edge material crushing and collecting device.

Background technique

Based on the fact that the current lithium battery slitting machine will continuously produce two 5~10mm side materials on both sides after slitting, currently a waste collection box is used under the slitting part of the slitting machine to collect, and then manually cleaned at regular intervals;

There are many problems in the use of this method. One is that the waste is directly discharged inside the equipment, which is easy to generate dust floating; the other is that the slitting machine is used at a speed of 50m/min, and the waste collection box will soon be full under this high-speed operation state, and then Manually requires frequent shutdowns to clean up waste, which affects production efficiency and quality stability; third, waste is easy to accumulate in the collection box, which is likely to cause edge material breakage, and edge material breakage will cause quality problems in the normal pole piece cutting next to it.

Utility model content

The purpose of this utility model is to provide a lithium battery pole piece slitting edge material crushing and collecting device to solve the problems of easy dust generation, low production efficiency, and low product qualification rate in the existing lithium battery production process. .

The technical scheme that the utility model adopts for realizing the above object is:

A lithium battery pole piece slitting edge material crushing and collecting device, which includes a crushing mechanism and a collecting mechanism, and the crushing mechanism and the collecting mechanism are connected through a dust pipeline; wherein, the crushing mechanism includes an edge material suction pipe and a grinder; The collection mechanism includes a negative pressure draft mechanism, and a debris collection box arranged under the negative pressure draft mechanism.

An exhaust duct is connected to the upper end of the negative pressure exhaust mechanism, and the exhaust duct communicates with the central wind circulation recovery system.

The pulverizer includes a pulverizing chamber, a moving knife mechanism and a spiral grinding mechanism are arranged inside the pulverizing chamber, and a power transmission assembly is provided at the lower part of the pulverizing chamber, and a driving motor is connected to the rear end of the power transmission assembly.

The scrap suction pipe is rotatably connected with the pulverizer.

The inner wall of the scrap suction pipe is provided with a plurality of misplaced "triangular" protrusions, and gradually rises from the suction pipe to the output end; the "triangular" protrusions are provided with arc-shaped slopes along the pipe wall.

With the "triangular" protrusion, which can be equivalent to the rotation of the pulverizer, the side material suction pipe can correct the horizontal side material to the vertical direction, so that the side material can be crushed more effectively. At the same time, due to the "triangular shape" "Protrusion The rear end is raised, which can effectively prevent debris from popping out from the inlet of the side material suction pipe when crushing.

A method for crushing and collecting lithium battery pole piece slitting edge material, which comprises the following steps:

(1) Set up a pulverizing mechanism, which includes a side material suction pipe and a pulverizer;

(2) Set up a collection mechanism, which includes a debris collection box and a negative pressure ventilation mechanism located on the upper part of the debris collection box;

(3) Set up a dust suction pipe, and the two ends of the dust suction pipe are respectively connected to the crushing mechanism and the collection mechanism;

(4) Connect the front end inlet of the side material suction pipe to the waste material outlet end of the slitting equipment, start the negative pressure ventilation mechanism and the pulverizer, the negative pressure ventilation mechanism generates negative pressure for ventilation, so that the side material enters the pulverizer from the side material suction pipe, The pulverizer crushes the side material to form chips, which are then discharged into the chip collection box under the action of draft negative pressure to complete the crushing and collection of the side material.

The beneficial effects of the utility model are as follows: 1. For crushing and floating, a sealed dust suction mechanism is adopted, and the edge material produced after cutting is sucked into the crushing device through a special pipeline, and the generated dust can be sucked into the dust suction system; 2. Aiming at the problem that the collection box is easy to be full, this mechanism has the function of crushing the waste. After the waste is crushed, it enters the dust collection box. After the waste is crushed, the space occupied by the collection box is greatly reduced, which improves the utilization rate of the collection box. More than 2 times, and because this mechanism adopts the crushing and pulling away structure, and adopts the installation method outside the equipment, the collection box will not be limited to the internal size of the slitting machine, and the shape and size of the collection box can be independently designed according to the needs; 3. Therefore, while improving the utilization rate of the waste collection box, the size of the collection box itself is increased to solve the problem of frequent manual stoppages to clean up waste, and the specifications of the collection box are customized according to actual production needs, so the collection box is independent of the slitting machine , so waste can be cleaned without downtime.
