Description

Technical Field

[0001] The utility model relates to an end face cutting machine, which belongs to the field of hollow fiber membrane processing. Background Art

[0002] Hollow fiber membrane refers to a membrane that looks like a fiber and has a self-supporting function. Hollow fiber membrane is a fiber filament with a hollow inner cavity processed from polysulfone and dimethylacetamide as raw materials, and then divided by a high permeability polymer, which has selective permeation characteristics. Since water vapor, hydrogen, ammonia and carbon dioxide permeate faster, while methane, nitrogen, argon, oxygen and carbon monoxide permeate slower, the fast permeation is separated from the slow permeation. In the process of processing hollow fiber membrane, it is necessary to cut the two ends of its package to avoid clogging at both ends of the hollow fiber membrane and ensure the flatness of the end face. In the prior art, the hollow fiber membrane cutting method is to place the hollow fiber membrane on a drum and transfer it to the bottom of the cutting knife for cutting, but the hollow fiber membrane has a certain length. If the hollow fiber membrane is not placed in the right position during the transmission process, the angle of the hollow fiber membrane will be offset when it is transmitted on the drum, resulting in the hollow fiber membrane cannot be vertically transmitted to the bottom of the cutting knife for cutting operation, resulting in an oblique cut, which reduces the quality of the finished hollow fiber membrane. Therefore, it is necessary to design an end face cutting machine that can limit the transmission angle of the hollow fiber membrane. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an end face trimming machine to solve the problems raised in the above-mentioned background technology. The present invention can limit the transmission angle of the hollow fiber membrane and improve the finished product quality of the hollow fiber membrane.

[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: an end face cutting machine, including a supporting base, a supporting plate is installed above the supporting base, a protective cover is installed on one side of the supporting plate, a cutting knife is installed on one side of the supporting plate, the cutting knife is located on the lower side of the protective cover, a filter is installed on the supporting plate, a dust suction structure is installed on the side of the supporting plate away from the cutting knife, a fixed base is installed above the supporting base, the fixed base is located on the side of the cutting knife away from the support plate, and a fixing part is installed above the fixed base.

[0005] Furthermore, the fixing member includes a fixing plate, a plurality of slots are formed on the fixing plate, a baffle is installed above the fixing plate, a push plate is installed inside the slot, a round rod is installed at the bottom of the push plate, and the other end of the round rod is installed in the sleeve.

[0006] Furthermore, the size of the push plate matches the card slot, and a spring is sleeved on the outside of the round rod and the sleeve, the top of the spring is connected to the fixed disk, and the bottom of the spring is connected to the fixed base.

[0007] Furthermore, multiple connecting plates are installed on both sides of the fixed plate, the connecting plates are located between the two card slots, multiple movable slots are opened on the fixed base, the other end of the connecting plate is inserted into the movable slot, the other end of the connecting plate is installed on the guide plate, and a handle is rotatably installed on the side of the fixed base away from the baffle.

[0008] Furthermore, a threaded sleeve is installed on the guide plate, the threaded sleeve is threadedly installed on the screw, the screw is rotatably installed in the fixed base, a main gear is installed on the screw, the main gear is located on the lower side of the threaded sleeve, the main gear is meshed with the transmission gear, the transmission gear is installed on the rotating rod, and a handle is installed on the end of the rotating rod away from the transmission gear.

[0009] Furthermore, the dust suction structure includes a delivery pipe, which is installed on a side of the support plate away from the cutting knife, the delivery pipe is located on the rear side of the filter, the other end of the delivery pipe is inserted into the support base, a connecting sleeve is installed at the bottom of the delivery pipe, a fan is installed at the bottom of the connecting sleeve, the bottom of the fan is installed on the support base, and a storage box is installed at the output end of the fan, and the storage box is installed inside the support base.

[0010] The beneficial effects of the utility model: an end face cutting machine of the utility model places the hollow fiber membrane to be cut above the fixed disk, and places the hollow fiber membrane to be transported inside the push plate. When the hollow fiber membrane needs to be transported under the cutting knife, the hollow fiber membrane is pushed from one end of the fixed disk so that the card slot limits the transport direction of the hollow fiber membrane, so that the transport direction of the hollow fiber membrane is perpendicular to the cutting knife, avoiding the situation where the hollow fiber membrane is tilted and transported to the bottom of the cutting knife for cutting operation, resulting in oblique cuts at both ends of the hollow fiber membrane.

[0011] When the end face of the hollow fiber membrane is processed, the handle is turned to drive the main gear to rotate, so that the screw drives the guide plate to move downward, so that the connecting plate applies a downward pulling force to the fixed plate, driving the fixed plate to press the spring downward, so that the push plate pushes the hollow fiber membrane out of the slot, reducing the time spent on removing the hollow fiber membrane after processing is completed, and improving the processing efficiency of the hollow fiber membrane.

[0012] When the cutting knife starts to cut the hollow fiber membrane, the fan will start to work synchronously. The delivery pipe is located at the rear side of the filter. The suction force generated by the fan will suck the dust generated during the cutting process from the delivery pipe into the fan, and transfer the dust to the storage box for storage, reducing the dust content in the air around the support base and improving the operating environment.
