Detailed Description

The following detailed description of the embodiments of the present invention will be given in order to provide those skilled in the art with a more complete, accurate and thorough understanding of the inventive concept and technical solutions of the present invention.

As shown in fig. 2, 3 and 4, the present invention is a plastic profile alloy pellet pelletizing die, which comprises a feeding plate 3, a compression plate 4, a forming plate 5 and an extrusion heating ring 6.

The granulation material passes through the feed plate 3 of mould and evenly gets into compression version 4, and through controlling certain compression ratio, compression plate 4 is closely knit with the material compression, and rethread profiled sheeting 5 carries out the shaping to the material, guarantees the stability ability of extruding material 10 simultaneously.

In order to solve the problems in the prior art, overcome the defects, realize the purposes of traction of extruded materials and avoiding material blockage, the invention adopts the technical scheme that:

as shown in fig. 3 and 4, in the plastic profile alloy pellet pelletizing die of the present invention, the plurality of discharge holes 9 on the forming plate 5 are parallel to each other and distributed on the same horizontal plane.

According to the granulating mould for the plastic profile alloy granules, the discharging mode adopts a parallel horizontal arrangement mode, traction can be realized by adopting traction equipment, and the plastic profile alloy granules are cooled and then cut, so that material blockage is avoided; change the first refrigerated mode of cutting of traditional granulation mode, import and export guiding mechanism through the water tank, pull the extrusion material at the uniform velocity through water tank cooling water, to the even cooling of extrudate, treat to cut the aggregate again after the cooling is abundant, effective control cooling time improves the granulation quality of alloy aggregate, also is favorable to prolonging the life of cutter.

Arrangement of the cooling water tank as shown in fig. 2 and 4:

and a cooling water tank 8 is arranged outside the discharge hole 9 on the forming plate 5, and extruded materials 10 discharged from the discharge hole 9 horizontally penetrate through the cooling water tank 8 in a linear shape.

A water tank guide block 7 is arranged at the material inlet end of the cooling water tank 8, and the extruded material 10 enters the cooling water tank 8 through a guide hole of the water tank guide block 7.

The arrangement of the tractor 11 as shown in fig. 5 (fig. 5 is an example of traction with rollers):

a tractor 11 is arranged behind the cooling water tank 8.

The extruded material 10 enters the cooling water tank 8 through the water tank guide block 7 and is uniformly and fully cooled. The outlet of the cooling water tank 8 is provided with a tractor 11 which can drag the horizontally arranged extrusion materials 9, thereby ensuring the smoothness of the extrusion materials and prolonging the startup period of the die.

The traction machine 11 is a traction roller which is distributed up and down, or a traction rolling belt which is distributed up and down; the extruded material 10 is clamped between the traction rollers which are distributed up and down and rotate, or between the traction rollers which are distributed up and down and move, so that the extruded material 10 moves correspondingly.

The traction rolling belt is formed by sleeving two rollers with rolling belts; the upper rolling belt and the lower rolling belt are respectively extruded to realize the traction of the extruded materials.

Arrangement of the pellet cutting apparatus as shown in fig. 6:

behind the said tractor 11, a pellet cutting device 12 is provided.

A cutting device is arranged behind the tractor 11 and used for cutting the cooled extruded materials to form material particles, so that alloy particle granulation is realized, meanwhile, due to the adoption of the mode of cooling before cutting, the extruded materials are formed, the shape of the particle materials cut by a cutter is complete, and the granulation quality is greatly improved.

Cutting the extruded material 10 into the required granules by a cutting knife 13; the size of the pellets is determined by the pulling speed, the rotational movement or the reciprocating movement speed of the cutter.

Because the cutting time of the granules is changed, the original cutting in a hot state is changed into the cutting after cooling, the cutter is not easy to stick, and the service life of the cutter is greatly prolonged.

The manufacturing method and the working principle analysis of the invention are as follows:

1. after the complete set of die is manufactured, the die is integrally assembled and is fixedly connected to the flange 1 of the extruder through the die flange 2 and the corresponding screw and nut.

2. Heating by the extrusion heating ring 6 (using electric heating); the mould is heated by the extrusion heating ring 6, so that the temperature of the mould is effectively controlled, and the flowability of the material in the mould is ensured.

3. After the heated material enters the die, the material is uniformly radiated into the compression plate 4 through the feeding plate 3; through reasonable compression angle design, the material is compressed compactly by the compression plate 4 and is ready for molding.

4. The discharge holes 9 on the forming plate 5 are horizontally arranged, so that the extruded materials 10 can be effectively ensured to be pulled, otherwise, the extruded materials cannot be pulled; meanwhile, the reasonable length design of the molded section enables the stability and molding quality of the material in the extrusion process to be improved.

5. The extruded material 10 smoothly enters the cooling water tank 8 through the guidance of the water tank guide block 7, and is sufficiently and uniformly cooled.

6. The outlet end of the cooling water tank 8 is provided with a traction machine 11 which generates traction force on the extruded material 10, and the extruded material is sufficiently and uniformly cooled in the cooling water tank by controlling the traction speed of the traction machine 11 and the extrusion rate of the extruder.

7. A cutting device, namely a granule cutting device 12 is arranged behind the tractor 11, and the alloy granules with required size are produced by controlling the rotating speed or reciprocating speed of a cutter blade of the cutting device to cut the materials.
