Description

Technical Field

[0001] The utility model relates to the technical field of lithium ion coating diaphragm production, in particular to a lithium ion diaphragm gravure roller transport trolley. Background Art

[0002] At present, the gravure roller coating process is the commonly used coating method in the lithium battery diaphragm industry. The micro-gravure roller takes the slurry out of the slurry box, and the fixed thickness scraper scrapes off the excess coating to form a coating window between the material box and the micro-gravure roller. Then the slurry is coated on the diaphragm under the action of the feeding pressure. The principle of micro-concave reverse coating is relatively simple. The capacity of the groove on the gravure roller is easy to control. The current gravure roller specifications correspond to different groove depths with different mesh numbers. The coating thickness is easier to control and the product precision is better. Due to the use of high-hardness alumina ceramic particles in the slurry, the anilox gravure roller is easy to wear, which will cause the coating to gradually become thinner during the continuous coating process, and then a new roller needs to be replaced; and the micro-grooves of the gravure roller are easily scratched and bumped. Production personnel often cause mechanical damage to the gravure roller during the transportation of the gravure roller. The gravure roller is expensive, and the maintenance and restoration cost after damage is relatively high.

[0003] In the actual production process of lithium battery separator coating, the gravure roller needs to be replaced frequently according to the product specifications of the production line and its own wear. During the operation, the gravure roller is usually moved manually. The operators often cause inevitable bumps and scratches on the gravure roller groove during the lifting, placement, and transfer of the gravure roller, thereby increasing the production line production and equipment maintenance costs.

[0004] At present, small transfer vehicles are also used in the process of transferring gravure rollers. The coating slurry of the micro-concave reverse coating of lithium-ion diaphragms is often an aqueous slurry. After the gravure roller is disassembled, the gravure roller itself needs to be cleaned of residual slurry. However, small gravure roller transfer vehicles often do not have a way to deal with the accumulated liquid, which will cause liquid accumulation problems and sometimes leakage problems. The operator is time-consuming and labor-intensive in the handling process.

[0005] In addition, the gravure roller transfer trolley usually only performs mechanical transportation during the transportation of the gravure roller, without taking into account the positioning rings near the back cutter grooves at the shaft ends on both sides of the gravure roller. The gravure roller often slides during the transportation process, causing varying degrees of wear on the shaft ends and positioning rings of the gravure roller. Sometimes the gravure roller even slips when parking, turning, or making an emergency stop, which not only damages the gravure roller, but also poses a potential safety hazard of injuring people.

[0031] See also Figure 1 , Figure 2 The figure is a schematic diagram of the structure of a lithium ion diaphragm gravure roller transport vehicle provided in a preferred embodiment of the present application. Figure 1 , Figure 2In the embodiment shown, the transfer trolley is mainly composed of a liquid accumulation container 1, a wheel set 2 and a support frame 3. The liquid accumulation container 1 is designed at the bottom of the transfer trolley, and its lower surface is equipped with a wheel set 2, so that the entire transfer trolley can be easily moved. The main function of the liquid accumulation container 1 is to collect and temporarily store the waste liquid dropped by the gravure roller 6 or the waste water remaining after cleaning, so as to avoid ground pollution and slipping accidents.

[0032] like Figure 4 , Figure 5 As shown, the top of the liquid accumulation container 1 is firmly connected to the support frame 3 through a plurality of vertical rods 4. The support frame 3 is designed with a front support block 30 and a rear support block 31, which are arranged opposite to each other to place a gravure roller 6 of a certain length. The front support block 30 and the rear support block 31 are respectively provided with a first notch 301 and a second notch 302 for placing the front end and the rear end of the gravure roller 6. In order to ensure the stability of the gravure roller 6 during transportation, a limiting groove 303 is provided in the first notch 301 and / or the second notch 302, and the limiting groove 303 is used to match the positioning ring 60 of the gravure roller 6, so as to effectively prevent the gravure roller 6 from sliding and bumping during movement.

[0033] In addition, in order to enhance the functionality of the transfer trolley, it is possible to consider installing a height-adjustable upright 4 to further improve the versatility and flexibility of the transfer trolley.

[0034] During the working process, the operator first gently places the gravure roller 6 to be transported into the notch of the support frame 3 to ensure that the positioning ring 60 of the gravure roller 6 is correctly docked with the limiting groove 303. Then, by pushing the transport trolley, the gravure roller 6 is smoothly moved to the destination. During the entire transport process, the gravure roller 6 is well protected to avoid bumps and scratches. At the same time, the liquid accumulation container 1 also effectively manages the waste liquid, ensuring a clean and safe working environment.

[0035] The lithium ion diaphragm gravure roller transfer trolley provided by the utility model not only greatly reduces the risk of damage to the gravure roller 6 during the transfer process, but also effectively improves work efficiency and safety, bringing significant economic and safety benefits to the lithium battery diaphragm coating production line.

[0036] like Figure 2 As shown, the liquid accumulation container 1 is composed of a membrane vehicle bottom plate 10, and two horizontal vertical plates 11 and two longitudinal vertical plates 12 are vertically connected around the membrane vehicle bottom plate 10 to form a closed container. In order to more effectively discharge the waste water or other liquids after cleaning, the membrane vehicle bottom plate 10 is designed to be tilted downward relative to the horizontal plane, and the tilt angle is ≥5°. At the inclined end, a through drainage hole 101 is opened, and a drainage pipe 102 is installed on the drainage hole 101, so that the waste liquid can be smoothly guided out and centrally processed to avoid environmental pollution and slip accidents.

[0037] like Figure 3 As shown, the wheel set 2 is composed of two directional front rollers 20 and two universal rear rollers 21 located at the front end of the film vehicle bottom plate 10. The front rollers 20 are fixedly connected to the film vehicle bottom plate 10 through the front roller connecting plate 22, and the rear rollers 21 are fixedly connected to the film vehicle bottom plate 10 through the rear roller connecting plate 23.

That is, in this embodiment, by adopting a downward bending design at the manual handrail, the downward bending angle is 45°, which allows the operator to save more effort under different usage conditions.

[0041] In addition, the mounting portion 50 is a C-shaped card plate, and the vertical pole 4 is a square tube, which can be clamped on the vertical pole 4, and a one-to-one corresponding second through hole is opened on the C-shaped card plate and the vertical pole 4. Each C-shaped card plate has a total of 6 second through holes and is connected to the vertical pole 4 with fastening screws.

[0042] Through the above design, the lithium-ion membrane gravure roller transfer cart of this embodiment not only effectively protects the gravure roller 6 from physical damage, but also effectively manages the waste liquid through the design of the liquid accumulation container 1, while providing an easy-to-operate and highly reliable transfer tool, which brings great convenience and safety to the transfer of the gravure roller 6 on the lithium-ion battery separator production line.
