Description

Technical Field

[0001] The utility model relates to the technical field of extruders, in particular to a fast-cooling halogen-free flame-retardant nylon material extruder. Background Art

[0002] Halogen-free flame-retardant nylon is a special plastic material, mainly used in the electronics, automotive, and construction industries to improve the flame retardancy and safety of products. During production and processing, the raw materials are added to an extruder and extruded through the extruder. To maintain the dimensional stability of the material and prevent skinning and scorching, the material needs to be rapidly cooled during extrusion. This solution specifically relates to a rapid cooling extruder for halogen-free flame-retardant nylon materials.

[0003] When using the existing halogen-free flame-retardant nylon material extruder, the continuous extrusion of the material will cause the cooling water temperature to rise, reducing the cooling effect of the material, making it inconvenient to support the material, accelerating the evaporation of water to cool it down, and residual moisture on the surface of the cooled material will affect subsequent processing and storage, making it inconvenient to blow dry. Utility Model Content

[0004] The main purpose of the utility model is to provide a fast-cooling halogen-free flame-retardant nylon material extruder, which can effectively solve the technical problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A fast-cooling halogen-free flame-retardant nylon material extruder comprises an extruder body, a cooling pool is installed at the front of the extruder body, an adjustment mechanism is installed inside the cooling pool, the adjustment mechanism comprises three groups of first rollers and three groups of adjustment seats, the three groups of first rollers are movably installed inside the cooling pool near the bottom end, the three groups of adjustment seats are respectively installed on both sides of the cooling pool, a screw is movably installed inside the adjustment seat, a knob is installed at the top of the screw, a slider is sleeved on the periphery of the screw, two support shafts are fixedly installed on the inner side of the slider, a rotating block is movably installed between the two support shafts, and a group of second rollers is movably installed between the two rotating blocks in each group of two adjustment seats.

[0007] As a further solution of the present invention, the number of each group of the first rollers and each group of the second rollers is two, and the three groups of the first rollers and the three groups of the second rollers are arranged at equal distances.

[0008] As a further solution of the present invention, the two adjustment seats are symmetrically installed, and the slider is sleeved on the outer periphery of the screw rod and is threadedly connected.

[0009] As a further solution of the present invention, the rotating block is located between the two supporting shafts and is movably rotatable, and both ends of the second roller are located between the two rotating blocks and connected by bearings.

[0010] As a further solution of the present invention, an air cooling mechanism is installed on the top of the cooling pool, and the air cooling mechanism includes two support frames and a number of through holes. The several through holes are respectively opened on both sides of the cooling pool. The two support frames are respectively fixedly installed on the top of the cooling pool on both sides. Three fixing plates are fixedly installed on the top of the two support frames. A fan is installed inside the fixing plate, and a dust net is installed on the top of the fan.

[0011] As a further solution of the present invention, the plurality of through holes are divided into three groups, and each group of through holes corresponds to the two end positions of each group of second rotating rollers.

[0012] As a further solution of the present invention, the three fixing plates are arranged at equal intervals, and the three fans are respectively located directly above the three groups of second rollers.

[0013] The beneficial effects of the utility model are as follows:

[0014] By setting an adjustment mechanism, the screw drives the slider to slide up and down, so that the height of the second roller can be changed. By using the second roller, it is convenient to support the extruded material and separate it from the cooling water. The support height can be easily adjusted, which is suitable for materials with different curvatures. Through the support of the support shaft and the rotation of the rotating block, a single adjustment seat can be adjusted to match the second roller.

[0015] By setting up an air cooling mechanism and cooperating with the support of the second roller, the fan blows external air to the surface of the material separated from the cooling water, accelerating the evaporation of moisture on the material surface, and then accelerating the cooling of the material. When the material is transported to the bottom of the fan at the front end, the residual moisture on the surface of the material can be blown dry, reducing the residual moisture on the surface of the material after extrusion and cooling.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, a fast-cooling halogen-free flame-retardant nylon material extruder includes an extruder body 1, a cooling pool 2 is installed at the front of the extruder body 1, an adjusting mechanism 3 is installed inside the cooling pool 2, the adjusting mechanism 3 includes three groups of first rollers 5 and three groups of adjusting seats 6, the three groups of first rollers 5 are movably installed inside the cooling pool 2 near the bottom, the three groups of adjusting seats 6 are respectively installed on both sides of the cooling pool 2, a screw 7 is movably installed inside the adjusting seat 6, a knob 8 is installed at the top of the screw 7, a slider 9 is sleeved on the periphery of the screw 7, two support shafts 10 are fixedly installed on the inner side of the slider 9, a rotating block 11 is movably installed between the two support shafts 10, and a group of second rollers 12 is movably installed between the two rotating blocks 11 in each group of two adjusting seats 6.

[0023] In this embodiment, there are two first rollers 5 and two second rollers 12 in each group, and the three groups of first rollers 5 and the three groups of second rollers 12 are arranged at equal intervals. The first rollers 5 and the second rollers 12 provide support and transportation for the extruded materials.

[0024] In this embodiment, the two adjustment seats 6 are installed symmetrically, and the slider 9 is sleeved on the outer periphery of the screw 7 and is threadedly connected. The rotation of the screw 7 drives the slider 9 to slide up and down, which is convenient for adjusting the height of the second roller 12.

[0025] In this embodiment, the rotating block 11 is located between the two support shafts 10 and is arranged to rotate movably. The two ends of the second roller 12 are located between the two rotating blocks 11 and are connected by bearings. The second roller 12 is connected by the rotation of the support shaft 10 and the rotating block 11, which facilitates the adjustment of the single adjustment seat 6.

[0026] In this embodiment, an air cooling mechanism 4 is installed on the top of the cooling pool 2. The air cooling mechanism 4 includes two support frames 13 and a plurality of through holes 14. The plurality of through holes 14 are respectively opened on both sides of the cooling pool 2. The two support frames 13 are respectively fixedly installed on the top of the cooling pool 2 on both sides. Three fixed plates 15 are fixedly installed on the top of the two support frames 13. A fan 16 is installed inside the fixed plate 15. A dustproof net 17 is installed on the top of the fan 16. The fan 16 draws in external air to blow the surface of the material straight, and cooperates with the support of the second roller 12 to separate the material from the cooling water, thereby accelerating the evaporation of the cooling water and cooling the material.

[0027] In this embodiment, the plurality of through holes 14 are divided into three groups. Each group of through holes 14 corresponds to the two ends of each group of second rollers 12. The internal air is discharged through the through holes 14, thereby accelerating the flow of the internal air.

[0028] In this embodiment, the three fixing plates 15 are arranged at equal intervals, and the three fans 16 are respectively located directly above the three groups of second rollers 12. The fans 16 blow air from the outside to cool the materials supported by the three groups of second rollers 12.

[0029] It should be noted that the utility model is a fast cooling halogen-free flame-retardant nylon material extruder. When in use, the raw materials for producing and processing halogen-free flame-retardant nylon materials are added to the extruder body 1, and the material is extruded through the extruder body 1 and transported to the cooling pool 2 for cooling. When supporting the material, the material passes through each group of first rollers 5 and second rollers 12. The second rollers 12 support the material and separate it from the cooling water, so that the surface moisture evaporates and accelerates the cooling of the material. Since the material has different bendability at different temperatures, when adjusting the support height, the knob 8 is rotated to make the screw 7 drive the slider 9 to slide up and down, and drive the corresponding end of the second roller 12 to rise and fall. The inclination of the second roller 12 is adapted and matched by the connection of the support shaft 10 and the rotation of the rotating block 11. When the material is supported by the second roller 12 and separated from the cooling water, the three fans 16 are started to blow external air to the surface of the material, so that the residual moisture on the surface of the material is accelerated to evaporate. The evaporation of water absorbs heat, thereby accelerating the cooling of the material. The material is cooled in sequence through the three fans 16 and the three groups of second rollers 12.
