Description

Technical Field

[0001] This utility model relates to the field of dust collection device technology, and in particular to a lithium-ion battery roller scraper dust collection device based on micro screw discharge. Background Technology

[0002] A lithium-ion battery is a rechargeable battery that primarily relies on the movement of lithium ions between the positive and negative electrodes to function. During charging and discharging, Li+ ions repeatedly insert and extract between the two electrodes: during charging, Li+ ions extract from the positive electrode, pass through the electrolyte, and insert into the negative electrode, leaving the negative electrode in a lithium-rich state; the reverse occurs during discharging.

[0003] Currently, dust problems are particularly serious in the production and manufacturing of lithium-ion batteries. The dust removal effect of the scraper dust removal device in the rolling process is not good. The main dust removal methods at present are negative pressure discharge, natural gravity discharge and manual cleaning. Dust bridging in the dust collection box leads to serious accumulation, and the high viscosity of the dust causes discharge blockage. Therefore, this utility model proposes a lithium-ion battery rolling scraper dust collection device based on micro screw discharge to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the serious dust problem in the existing technology during the production of lithium-ion batteries, where the dust removal effect of the scraper dust removal device in the rolling process is not good. Currently, the main dust removal methods are negative pressure discharge, natural gravity discharge, and manual cleaning. These methods result in severe dust accumulation due to bridging in the dust collection box and high dust viscosity leading to discharge blockage. Therefore, this invention proposes a lithium-ion battery rolling scraper dust collection device based on micro screw discharge.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A dust collection device for lithium-ion batteries based on a micro-screw discharge roller scraper includes a dust collection box, a motor, and a dust bag. The motor is fixedly installed on the left side of the dust collection box, and the dust bag is installed on the right side of the dust collection box. The dust collection device also includes... The installation mechanism and the unlocking mechanism are provided in two sets, and both the installation mechanism and the unlocking mechanism are used in conjunction with the dust collection box. A filtration mechanism, comprising: a filter screen, two connecting rods, and two fixing rods; The bottom of the filter screen slides in contact with the top of the dust collection box. Two connecting rods are fixedly installed on the left and right sides of the filter screen, respectively. Two fixing rods are fixedly installed on the dust collection box, and the connecting rods slide in contact with the fixing rods.

[0006] As a preferred embodiment of this utility model, the installation mechanism includes: a bonding frame, a spring, and a fixing block; The bonding frame is slidably connected to the dust collection box. The bonding frame is fixedly connected to the spring, the spring is fixedly connected to the fixing block, the fixing block is fixedly connected to the dust collection box, and the bonding frame cooperates with the docking rod.

[0007] Furthermore, the installation mechanism uses a spring to drive the bonding frame, ensuring close contact between the bonding block and the docking rod, thus achieving rapid fixing and sealing of the filter screen. The spring provides continuous clamping force to prevent dust leakage, while the fixing block ensures installation stability and improves maintenance efficiency.

[0008] As a preferred embodiment of this utility model, the unlocking mechanism includes: two driving rods, two rotating rods, and a connecting rod; Two drive rods are fixedly connected to two bonding frames respectively, and two rotating rods are rotatably connected to the left and right sides of the dust collection box respectively.

The sliding contact between the round rod and the rotating rod achieves linkage, so that when the connecting rod and the rotating rod are pressed down, the rod and the fitting frame can be disengaged from the docking rod. This can simultaneously release the locking state of the installation mechanisms on both sides, realizing one-click quick disassembly of the filter screen, which is convenient for cleaning and maintenance and reduces equipment downtime.

[0010] In a preferred embodiment of this utility model, a round rod is fixedly installed at the bottom of the driving rod, and the outer side of the round rod slides in contact with the inner wall of the rotating rod.

[0012] In a preferred embodiment of this utility model, a bonding block is fixedly installed on the top of the bonding frame, and the bonding block slides in contact with the docking rod.

[0013] Furthermore, the bonding block is made of wear-resistant material and forms a surface contact with the mating rod to enhance the sealing effect and prevent dust from escaping from the interface.

[0014] As a preferred embodiment of this utility model, vertical sliding grooves are provided on both the left and right sides of the dust collection box, and the two fitting frames are slidably connected to the inner walls of the two vertical sliding grooves respectively.

[0015] Furthermore, the vertical groove provides precise guidance for the bonding frame, ensuring that the installation mechanism moves in a straight line and avoiding jamming.

[0016] As a preferred embodiment of this utility model, a rectangular groove is provided on the top of the dust collection box, and the outer side of the filter screen slides in contact with the inner wall of the rectangular groove.

[0017] Furthermore, the rectangular groove and the filter screen are fitted with a gap, which ensures smooth installation and maintains a good seal, thereby improving dust collection efficiency. Beneficial effects

The spring 8 provides continuous clamping force to prevent dust leakage, and the fixing block 9 ensures installation stability and improves maintenance efficiency.

[0024] To unlock the filter 4, the unlocking mechanism includes: two driving rods 10, two rotating rods 11, and a connecting rod 12; Two driving rods 10 are fixedly connected to two bonding frames 7 respectively. Two rotating rods 11 are rotatably connected to the left and right sides of the dust collection box respectively. The left and right ends of the connecting rod 12 are fixedly connected to the sides of the two rotating rods 11 that are close to each other. The unlocking mechanism drives the two rotating rods 11 to move synchronously through the connecting rod 12. The linkage is achieved by the sliding contact between the round rod and the rotating rod 11. When the connecting rod 12 and the rotating rod 11 are pressed, the driving rod 10 and the bonding frame 7 can be disengaged from the docking rod 5. The locking state of the two side mounting mechanisms can be released at the same time, realizing one-click quick disassembly of the filter screen 4, which is convenient for cleaning and maintenance and reduces equipment downtime.
