Description

Technical Field

[0001] This utility model belongs to the field of halogen-free flame-retardant TPU sheath material processing technology, specifically relating to a screening mechanism for processing halogen-free flame-retardant TPU sheath material. Background Technology

[0002] The screening mechanism for processing halogen-free flame-retardant TPU sheathing material is mainly used to classify raw material particles according to specific particle sizes, ensuring uniform particle size and preventing excessively large or small particles from entering subsequent processing stages. This enhances the performance stability of the final product, such as flame retardancy, flexibility, and mechanical strength. It has wide applications in cable sheathing production, industrial plastic product processing, and military fields, and can significantly improve production efficiency and product quality.

[0003] In some existing screening facilities, when raw materials are received and screened, the materials usually fall to the top of the screen and rely on vibration to gradually spread evenly. During this process, arc-shaped friction occurs between the raw material particles, and the continuous vibration of the device exacerbates this effect. This causes the fine particulate dust that was originally attached to the surface of the raw materials to easily fall off and spread to the surrounding environment and the inner wall of the device with the airflow or vibration, causing environmental and equipment pollution. This makes it inconvenient for production environment maintenance and subsequent cleaning, and affects the cleanliness and efficiency of the production process. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a screening mechanism for processing halogen-free flame-retardant TPU sheathing materials. This addresses the issue raised in the background section where existing screening mechanisms typically cause raw materials to fall to the top of the screen and require vibration to spread evenly. During this process, arc-shaped friction occurs between the raw material particles, and the continuous vibration of the device exacerbates this effect. This causes fine particulate dust that was originally attached to the surface of the raw material to easily fall off and spread to the surrounding environment and the inner wall of the device with airflow or vibration, resulting in environmental and equipment pollution. This causes inconvenience for production environment maintenance and subsequent cleaning, affecting the cleanliness and efficiency of the production process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screening mechanism for processing halogen-free flame-retardant TPU sheath material, comprising a main body and a dust removal mechanism disposed on the top of the main body for collecting particulate dust generated by friction and vibration of falling material and discharging it into a filtration device. The dust removal mechanism includes an outer frame fixedly connected to the top of the substrate, a guide pipe fixedly connected to one side of the top of the outer frame, an inner frame fixedly connected to the inner side of the outer frame, two inner frames symmetrically arranged, a dust exhaust fan fixedly connected to the inner side of the inner frame, a sealing pipe fixedly connected to one side of the inner frame, a guide pipe fixedly connected to one side of the sealing pipe, and a connecting hose fixedly connected to one side of the guide pipe.

[0006] Preferably, the main body mechanism includes a base plate, a vibrating foot fixedly connected to the top of the base plate, a plurality of vibrating feet symmetrically arranged, a screen frame fixedly connected to the top of the vibrating foot plate, a vibrating motor fixedly connected to the bottom of the screen frame, and a plurality of screens symmetrically arranged on the inner side of the screen frame.

[0007] Preferably, the guide tube has an inverted frustum structure with a top diameter larger than a bottom diameter, and an outer frame is fixedly connected to the bottom of the guide tube.

[0008] Preferably, a dust collection cover is fixedly connected to the bottom of the inner frame, and an outer frame is fixedly connected to the outside of the inner frame.

[0009] Preferably, a support column is fixedly connected to the top of the dust collection hood, and several support columns are symmetrically arranged. An outer frame is fixedly connected to the top of the support column.

[0010] Preferably, a curtain is fixedly connected to one side of the outer frame.

[0011] Preferably, a flap is rotatably connected to the inner side of the guide tube.

[0012] Preferably, a support frame is fixedly connected to the outside of the guide tube, and two support frames are symmetrically arranged. A guide tube is fixedly connected to one side of the support frame.

[0013] Compared with the prior art, this utility model provides a screening mechanism for processing halogen-free flame-retardant TPU sheath material, which has the following beneficial effects:

[0014] 1. This utility model, by setting up a dust exhaust fan, installs the main body mechanism in the working environment, and then turns on the vibration motor in conjunction with the vibration foot to drive the screen frame to vibrate as a whole. Several symmetrically arranged screens are used to screen and process the halogen-free flame-retardant TPU sheath material. The halogen-free flame-retardant TPU sheath material raw material is fed into the top of the guide pipe. The material impacts the flapper, causing the flapper to flip inside the guide pipe and creating gaps between the guide pipes. The material then flows into the inner wall of the guide pipe through the gaps and finally falls onto the top of the screen. The dust exhaust fan is turned on to start the operation. The particulate dust generated during the falling of the material and the even spreading on the top of the screen is drawn into the inner frame through the dust collection hood, and then transported to the guide pipe through the inner frame. Finally, it is discharged into the corresponding air filtration equipment for purification through the connecting hose. This can effectively reduce the occurrence of dust adhering to the surface of the material being dispersed into the external environment during the falling and vibrating spreading process, thereby reducing the degree of pollution to the inner wall of the equipment and the external environment.

[0015] 2. By setting up a support frame, this utility model can effectively ensure the stability of the guide tube's position during the vibration of the device and reduce its swing amplitude.

[0016] 3. By setting up a flap, the material impacts the flap during the feeding process, causing it to flip inside the guide pipe and creating a gap between the material and the guide pipe. The material falls through the gap. After feeding is completed, the pressure on the flap disappears and it resets, sealing the inner wall of the guide pipe. This effectively reduces the amount of dust that seeps out from the inner wall of the guide pipe, which is directly exposed to the external environment, after feeding.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. Attached Figure Description

The dust removal mechanism 2 includes an outer frame 201 fixedly connected to the top of a substrate 101, a guide pipe 202 fixedly connected to one side of the top of the outer frame 201, an inner frame 203 fixedly connected to the inner side of the outer frame 201, two inner frames 203 symmetrically arranged, a dust exhaust fan 204 fixedly connected to the inner side of the inner frame 203, a sealing pipe 205 fixedly connected to one side of the inner frame 203, a guide pipe 206 fixedly connected to one side of the sealing pipe 205, and a connecting hose 207 fixedly connected to one side of the guide pipe 206. The main body 1 is installed in the working environment, and then the vibration motor 104 is turned on in conjunction with the vibration foot 102 to drive the entire screen frame 103. Vibration is used to screen the halogen-free flame-retardant TPU sheath material through several symmetrically arranged screens 105. The raw material is fed into the top of the guide pipe 202. The material impacts the flap 6, causing the flap 6 to flip inside the guide pipe 202 and creating gaps between the guide pipes 202. The material then flows into the inner wall of the guide pipe 202 through the gaps and finally falls onto the top of the screens 105. The dust exhaust fan 204 is turned on to start the operation. The particulate dust generated during the falling of the material and the even spreading on the top of the screens 105 is drawn into the inner frame 203 through the dust collection hood 3. After being transported through the inner frame 203 to the guide pipe 206, it is finally discharged into the corresponding air filtration equipment through the connecting hose 207 for purification. This can effectively reduce the occurrence of dust adhering to the surface of the material being dispersed into the external environment during the falling and vibration spreading process, thereby reducing the degree of pollution to the inner wall of the equipment and the external environment.

The main body mechanism 1 is installed in the working environment, and then the vibrating motor 104 is turned on to drive the screen frame 103 to vibrate as a whole in conjunction with the vibrating foot 102. The halogen-free flame-retardant TPU sheath material is screened and processed through the several symmetrically arranged screens 105.

[0031] In this invention, preferably, a flap 6 is rotatably connected to the inner side of the guide pipe 202. During the feeding process, the material impacts the flap 6, causing it to flip inside the guide pipe 202 and creating a gap between it and the guide pipe 202. The material falls through the gap. After feeding is completed, the pressure on the flap 6 disappears and it resets, sealing the inner wall of the guide pipe 202.

A guide tube 202 is fixedly connected to one side of the support frame 7, which can effectively ensure the stability of the position of the guide tube 206 during the vibration of the device and reduce its swing amplitude.

[0033] The working principle and usage process of this utility model are as follows: In use, the main body 1 is installed in the working environment. Then, the vibration motor 104, in conjunction with the vibration foot 102, drives the screen frame 103 to vibrate as a whole. Several symmetrically arranged screens 105 are used to screen and process the halogen-free flame-retardant TPU sheath material. The halogen-free flame-retardant TPU sheath material raw material is fed into the top of the guide pipe 202. The material impacts the flapper 6, causing the flapper 6 to flip inside the guide pipe 202, creating gaps between the guide pipes 202. The material then flows into the guide pipe 202 through these gaps. The material falls onto the top of the screen 105, and the dust exhaust fan 204 is turned on to start the operation. The particulate dust generated during the falling of the material and its even spreading on the top of the screen 105 is drawn into the inner frame 203 through the dust collection hood 3. After being transported through the inner frame 203 to the guide pipe 206, it is finally discharged into the corresponding air filtration equipment through the connecting hose 207 for purification. This can effectively reduce the occurrence of dust adhering to the surface of the material being dispersed into the external environment during the falling and vibrating spreading process, thereby reducing the degree of pollution to the inner wall of the equipment and the external environment.
