Description

Technical Field

[0001] This utility model relates to the field of diversion control devices, and in particular to a pressure equalization diversion control device. Background Technology

[0002] In the lithium battery manufacturing industry, burrs are usually generated when cutting electrode tabs on electrode sheets. The generation of burrs when cutting electrode tabs on electrode sheets is mainly related to equipment parameters, tool condition, material characteristics and process control. For example, abnormal mold clearance, tool wear, improper punching method, deviation of mold pressure plate flatness or insufficient pressure can all lead to the inability to effectively compact the cut edge. To reduce burrs at the edges of electrode cutting, ceramic adhesive slurry can be applied to the cutting area. Automated electrode cutting lines typically employ multiple adhesive application mechanisms, each equipped with a corresponding slurry container. This container supplies the required ceramic adhesive slurry to the nozzles of each application device. However, as the pressure of the slurry in the flow channel increases with the length of the pipe, hydraulic pressure loss also increases. Narrowing the flow channel further exacerbates the pressure loss, leading to variations in pressure within the channel. A common practice is to equip each application device with a throttling and pressure regulating device. However, this device is prone to clogging due to the presence of suspended liquid, and such a configuration is costly and not conducive to the long-term development of the industry. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pressure equalization and flow splitting control device.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The pressure equalization and diversion control device includes a lower mold for holding slurry, one side of the lower mold is provided with at least one diversion channel, the diversion channel connects the top surface and one side of the lower mold, the top of the lower mold is provided with a pressure equalization chamber for holding slurry, an upper mold is mounted on the lower mold, diversion valve rods are movably mounted on the upper mold at positions corresponding to each diversion channel, a diversion valve for blocking the diversion channel is installed at the bottom of the diversion valve rod, and a sealing gasket is installed between the upper mold and the lower mold.

[0005] Preferably, at least one differential support is installed on the top surface of the upper mold of the distributor, and a differential head is installed on the differential support. The lower end of the differential head is connected to the upper end of the distributor valve stem through a coupling.

[0006] Preferably, the sealing gasket is provided with a diversion groove at a position corresponding to each diversion channel. Each diversion groove connects the pressure equalization chamber to the corresponding diversion channel, and the pressure equalization chamber supplies slurry to the diversion channel through the diversion groove.

[0007] Preferably, the lower mold of the distributor is provided with a diversion groove at a position corresponding to each diversion channel. Each diversion groove is connected to the equalizing chamber and the corresponding diversion channel. The equalizing chamber supplies slurry to the diversion channel through the diversion groove.

[0008] Preferably, the upper mold of the diverter is provided with a valve stem channel for the diverter valve stem to slide up and down, the circumference of the diverter valve stem is provided with an annular groove, and an O-ring is fitted on the diverter valve stem, with the O-ring located in the annular groove; there is one or more annular grooves and one or more O-rings.

[0009] Preferably, the lower end of the diversion valve has an outer chamfer on its circumference, and the feed inlet of the diversion channel opposite to the diversion valve has an inner chamfer, so that the outer shape of the lower end of the diversion valve matches the inner shape of the feed inlet of the diversion channel.

[0010] Preferably, the lower mold of the distributor is provided with a feed hole, which is connected to the pressure equalization chamber and is used to supply slurry to the pressure equalization chamber.

[0011] Preferably, the outlet of the diversion channel is equipped with a material pipe connector.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: 1. By providing diversion grooves on the sealing gasket at positions corresponding to each diversion channel, or by providing diversion grooves on the lower mold of the diverter at positions corresponding to each diversion channel, the equalizing chamber can automatically supply slurry to the diversion channels through the diversion grooves. Simultaneously, diversion valve stems are movably mounted on the upper mold of the diverter at positions corresponding to each diversion channel, and valve stem channels for the diversion valve stems to slide and rise are provided on the upper mold of the diverter. A coupling is provided at the upper end of the diversion valve stem to connect and install a micrometer head, allowing the diversion valve to rise and fall through the diversion valve stem, thereby adjusting the diversion valve and the diversion flow. The gap between the feed inlets of the channels is used to control the flow rate of the slurry in the diversion channels, thereby controlling the hydraulic pressure of the slurry at the outlet of the diversion channels. This allows each diversion valve rod to independently control the flow rate and hydraulic pressure of the slurry in its corresponding diversion channel, providing slurries with different hydraulic pressures for different scenarios. This achieves the goal of high versatility, reduces equipment costs, and effectively solves the problems of high equipment costs caused by the need for a throttling and pressure regulating device to reduce pressure loss in the flow channels in multiple glue coating mechanisms on automated electrode cutting production lines, as well as the problems of low production efficiency, low capacity, and time-consuming and labor-intensive unblocking due to easy clogging of the throttling and pressure regulating devices.

[0013] 2. By providing at least one annular groove on the circumference of the diversion valve stem and sleeved with at least one O-ring, with one O-ring installed in one annular groove, the sealing between the valve stem channel and the diversion valve stem is improved, preventing the slurry in the diversion groove from leaking into the valve stem channel, and ensuring the hydraulic stability of the slurry in the pressure equalization chamber.
