Embodiment 1
[0026] Such as Figure 1 to Figure 2 As shown, the present invention provides a granulator, comprising: a feed hopper 1, a barrel 2 communicated with the feed hopper 1, a buffer chamber 3 communicated with the feed barrel 2, and a granulation chamber 4 communicated with the buffer chamber 3 . The raw material enters the barrel 2 from the feed hopper 1, and is transported to the buffer chamber 3 after being heated in the barrel 2. After being squeezed in the buffer chamber 3, it enters the granulation chamber 4 for granulation.
[0027] One side of the barrel 2 is provided with a first motor 6 . The first motor 6 is connected to the first rotating shaft 61 . The first rotating shaft 61 extends into the inside of the barrel 2 . The helical blade 8 is arranged on the first rotating shaft 61 . The first motor 6 drives the first rotating shaft 61 to rotate, and transmits the raw material to the buffer chamber 3 through the helical blade 8 .
[0028] A second motor 5 is provide...
Embodiment 2
[0033] A manufacturing process of a granulator barrel, the steps are as follows:
[0034] ① Roll forming of barrel
[0035] Ductile cast iron is used as raw material, and the barrel is made by roll forming technology. One end of the barrel has a vertical opening, and the other end has a horizontal opening;
[0036] ②, Spraying treatment on the inner wall of the barrel
[0037] Use electrostatic spraying technology to spray the inner wall of the barrel, and leave it for 10 days naturally after spraying;
[0038] The preparation method of the spraying liquid is: 25 parts of epoxy resin, 5 parts of titanium dioxide, 10 parts of methylolated phenol, 5 parts of leveling agent, 15 parts of solvent, 5 parts of 5,7-dihydroxyflavone and trifluoropropanesulfone Put 5 parts of Long in a mixing container, stir and mix evenly;
[0039] ③, heat treatment
[0040] Place the barrel in a heat treatment furnace for heat treatment at 200°C for 0.5h, then let it cool naturally.

Abstract
The invention discloses a manufacturing process for a granulator material barrel, and relates to the technical field of granulation. The manufacturing process comprises the following steps: (1) rolling forming for the material barrel: taking nodular cast iron as a raw material, and preparing the material barrel through a rolling forming technology, wherein an opening in the vertical direction is formed in one end of the material barrel, and an opening in the horizontal direction is formed in the other end of the material barrel; (2) spraying treatment for the inner wall of the material barrel: carrying out spraying treatment on the inner wall of the material barrel through an electrostatic spraying technology, and naturally placing the material barrel for 10 days after spraying is concluded, wherein a preparation method for a spraying liquid comprises the following steps: placing 25 parts of epoxy resin, 5 parts of titanium dioxide, and the like in a stirring container, and uniformly stirring and mixing; and (3) heat treatment: placing the material barrel in a heat treatment furnace and carrying out heat treatment for 0.5h at 200 DEG C, and naturally cooling to obtain the product. The material barrel is novel in structural design and long in service life. The manufacturing process is reasonable in procedure arrangement, and the spraying liquid with a special design is sprayed on the inner wall of the material barrel, so that the wear resistance of the inner wall of the material barrel is remarkably enhanced.
Description
technical field [0001] The invention relates to the technical field of granulation, in particular to a manufacturing process of a granulator barrel. Background technique [0002] A granulator is a machine that turns plastic film and other raw materials into plastic granules. Its working principle is to transport plastic film and other raw materials to the material cylinder for heating and melting, after the raw materials are melted, they are extruded in the buffer chamber, and then form plastic granules through the granulation holes on the cutter. [0003] During the granulation process of the granulator currently on the market, after the raw material enters the material barrel, it passes through the screw blade on the rotating shaft arranged in the material barrel to guide the raw material to the buffer chamber. However, in the actual production process, raw materials are easy to deposit at the bottom of the barrel, and this part of raw materials cannot be sent into the bu...
