Description

Technical Field

[0001] The utility model belongs to the technical field of switching valves, and particularly relates to a three-way switching valve for a melt filter. Background Technique

[0002] A melt filter is an important device in high-speed spinning and fine denier filament spinning, used for continuous filtration of polymer melt to remove impurities and unmolten particles in the melt, so as to improve the spinning performance of the melt and ensure the spinning quality.

[0003] Before the melt filter operates, the melt material needs to be transported into the filter first. Therefore, a three-way switching valve is used to facilitate the control of the melt material transportation.

[0004] However, during the use of the three-way switching valve, since there are three independent adjustment mechanisms, during the use process, the staff needs to perform adjustment operations separately. Therefore, not only does it increase the operation difficulty, but also it will waste the working time of the staff, thereby reducing the working efficiency of the staff. Content of the Utility Model

[0005] The purpose of the utility model is to provide a three-way switching valve for a melt filter to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A three-way switching valve for a melt filter, including a support base, a discharge pipe is fixedly connected inside the support base, and a switching component is arranged outside the discharge pipe;

[0007] The switching component includes a support column, the support column is fixedly connected to the top of the support base, the support column is communicated with the discharge pipe, a transmission box body is fixedly connected to the top of the support column, a transmission rod is connected inside the support column, the bottom of the transmission rod is fixedly connected with an adjustment disc inside the discharge pipe, a discharge port is opened at the top of the adjustment disc, discharge holes are opened on the side surface of the adjustment disc, a discharge groove is opened on the other side surface of the adjustment disc, a diversion groove is opened on the other side surface of the adjustment disc, a bearing is fixedly connected to the side surface of the transmission rod, a sealing gasket is fixedly connected to the bottom of the bearing, the transmission rod penetrates through the top of the support column and is fixedly connected with a worm gear disc, a worm is connected inside the transmission box body, and a steering wheel is fixedly connected to one end of the worm.

[0008] As a preferred implementation manner, the discharge holes are communicated with the discharge port, and the worm is meshed with the worm gear disc.

[0009] As a preferred embodiment, a fixing component is provided at the bottom of the worm wheel disc. The fixing component includes a first engaging tooth and an auxiliary box body. The auxiliary box body is fixedly connected to the bottom of the worm wheel disc. The auxiliary box body is fixedly connected below the auxiliary box body and located at the top of the support column. The transmission rod penetrates through the auxiliary box body.

[0010] As a preferred embodiment, a limiting sliding groove is formed inside the auxiliary box body. A moving block is movably connected inside the limiting sliding groove. A second engaging tooth is fixedly connected to the top of the moving block. The second engaging teeth are distributed in a circumferential array on the top of the moving block. A spiral spring is fixedly connected to the bottom of the moving block. The spiral springs are distributed in a circumferential array on the bottom of the moving block.

[0011] As a preferred embodiment, the discharge pipe includes a feed pipe, a first shunt pipe, a second shunt pipe, and a water guide groove. The feed pipe is fixedly communicated with the top of the support base. The first shunt pipe is fixedly communicated with the left side of the support base.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] In the present utility model, by providing a switching component, during the use process, the staff only needs to turn the steering wheel, so that the steering wheel drives the worm to rotate. Also, because of the meshing connection between the worm and the worm wheel disc, the transmission rod is driven to rotate. During the rotation of the transmission rod, the adjusting disc can be driven to rotate. When the adjusting disc rotates to a certain angle and the discharge port is located at the bottom of the feed pipe, the melt material inside the feed pipe will be discharged from the second shunt pipe through the discharge hole. When the discharge groove is located at the bottom of the feed pipe, the melt material will be discharged from the first shunt pipe. When the shunt groove is located at the bottom of the feed pipe, the melt material will be discharged from both the first shunt pipe and the second shunt pipe respectively. This effectively improves the convenience and practicality of the device for controlling the flow of the melt material, reduces the adjustment operation, improves the working efficiency of the staff, and facilitates the use of the staff.

[0015] In the present utility model, by providing a fixing component, during the rotation of the worm wheel disc, the first engaging tooth will be driven to rotate synchronously. Through the first engaging tooth, a downward pressure can be exerted on the second engaging tooth during the rotation of the worm wheel disc, thereby preventing the worm wheel disc from being blocked. After the worm wheel disc finishes rotating, the second engaging tooth is ejected by the spiral spring, and the first engaging tooth can be clamped, thereby preventing the worm wheel disc from reversing and resetting, effectively improving the practicality and stability.
