Description
Technical Field
[0001] The utility model relates to the technical field of nylon chip processing, in particular to a screw granulating device for processing flame-retardant nylon chips. Background Technique
[0002] Traditional nylon chip granulating devices usually adopt a single type of screw structure, and process nylon chips into particles through heating and extrusion. Although the structure is simple and the operation is convenient, there are many limitations in terms of function.
[0003] First of all, traditional devices can only produce particles of a single specification, which is difficult to meet the market's demand for diversified nylon particles; secondly, due to the limitation of screw design, the granulating speed is slow and the production efficiency is low; in addition, traditional devices are limited in function in adjusting the size and shape of particles, and it is difficult to produce strip-shaped or other special-shaped particles. These disadvantages make it difficult for traditional devices to meet the requirements of modern industry for the efficient and diversified production of nylon particles.
[0004] In view of the above problems, we have introduced a screw granulating device for processing flame-retardant nylon chips. Content of the Utility Model
[0005] The utility model discloses a screw granulating device for processing flame-retardant nylon chips, aiming to solve the technical problems in the background technique.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0007] A screw granulating device for processing flame-retardant nylon chips includes a housing. One end of the housing is connected with a sealing end through screws, and the other end of the housing is connected with a discharge end through screws. A rotating roller is arranged inside the housing, and connecting gears are fixedly connected to the rotating rollers. The two connecting gears are meshed with each other. Rotating bearings are connected inside the sealing end, and the rotating rollers are rotatably connected to the sealing end through the rotating bearings. One end of each rotating roller is fixedly connected with a granulating screw.
[0008] By driving one of the rotating rollers to rotate, through the meshing of the connecting gears on the rotating rollers, the two rotating rollers can be driven to rotate in opposite directions at the same time. In this way, the granulating screws can be driven to rotate in opposite directions. Through the opposite rotation of the granulating screws, the nylon chips can be extruded and cut into particles of corresponding sizes.
[0009] In a preferred scheme, the granulating screws are rotatably connected to the inner wall of the housing, and one end of each granulating screw extends into the inside of the discharge end.
[0010] The granulating screws need to maintain a rotating relationship with the inner wall of the housing, and there should be no large gaps to avoid material leakage.
[0011] In a preferred embodiment, the granulating screw includes a large-pitch flat screw structure, a short-pitch cutting screw, and a large-angle screw structure.
[0012] The large-pitch flat screw is used to manufacture larger particles. The large-pitch flat screw mainly realizes the granulation of nylon materials by heating, extruding, and shaping. The short-pitch cutting screw is used to manufacture smaller particles, mainly by cutting nylon into small particles of different specifications. The large-angle screw can be used to make strip-shaped nylon particles. Its included angle is small. Compared with the above two, such a structure can improve the granulation speed.
[0013] In a preferred embodiment, sealing gaskets are embedded at both ends of the housing.
[0014] By setting the sealing gaskets, it can be ensured that the gas emitted by the nylon material when heated during the processing of this device will not disperse.
[0015] In a preferred embodiment, the discharging end is set at a bending angle convenient for discharging.
[0016] Through such a setting, it is convenient for the discharging of nylon particles.
[0017] In a preferred embodiment, a feed flange is fixedly connected to the top of the housing, and an air inlet interface is provided on the plugging end.
[0018] The feed flange is used to feed nylon chips, and the air inlet interface can send high-temperature air into this device to facilitate the heating of nylon materials.
[0019] In a preferred embodiment, a mounting seat is fixedly connected to the bottom of the housing.
[0020] By setting the mounting seat, it is convenient to fix this device.
[0021] The screw granulating device for processing flame-retardant nylon chips provided by the present utility model has the following advantages:
[0022] When in use, first feed nylon chips through the feed flange, and send high-temperature air into the device through the air inlet interface to heat the nylon. Then, drive the gears to mesh through a rotating roller, drive the two rotating rollers to rotate in opposite directions at the same time, thereby driving the granulating screws to rotate towards each other, extruding and cutting the nylon chips to make the required particles. Among them, the large-pitch flat screw is used to manufacture larger particles, the short-pitch cutting screw is used to manufacture smaller particles, and the large-angle screw is used to make strip-shaped particles. Such a design enables the device to have diversified and efficient granulation functions. BRIEF DESCRIPTION OF THE DRAWINGS
