Description

Technical Field

[0001] This utility model relates to a cold cutting granulation auxiliary device, specifically a cold cutting granulation strip support roller. Background Technology

[0002] Cold cutting of plastic granules is a common plastic processing method, mainly used to cut plastic materials into small granules for subsequent melting and molding. Cold cutting mainly includes cold drawing and pelletizing, which involves heating and melting plastic and extruding it into strips. The extruded plastic is then cooled by water or air cooling. During the extrusion, cooling, and traction process, the material needs to be cooled and shaped by water in a water tank, and then dehydrated and air-dried before finally being pelletized. During the traction, cooling, and air-drying process, rollers are used to support the material strips. Cold drawing strip rollers are key equipment in the plastic extrusion and pelletizing process, mainly used to support and guide the extruded plastic strips to ensure their smooth entry into the pelletizer. Existing rollers mainly use simple bearing structures, achieving their supporting function as the strip rotates under traction. However, due to prolonged exposure to water and the friction of the warm strips under traction, the rollers are prone to corrosion, wear, and deformation. Utility Model Content

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This utility model discloses a cold-cut granulation strip support roller, comprising a base with two supports arranged opposite each other on the base, and a support roller positioned between the two supports. The support roller includes a central shaft and multiple baffles arranged on the central shaft. The central shaft is a hollow structure, with one end closed and an air inlet valve at the other end. An air outlet is located on the central shaft between two adjacent baffles. In use, compressed gas is supplied by an air pump. The compressed gas enters the central shaft of the support roller through the air inlet valve and is ejected from the air outlet between two adjacent baffles, achieving an upward blowing effect. When the granulation strip passes between two adjacent baffles, the gas ejected from the air outlet has an upward blowing force, which reduces the friction between the granulation strip and the support roller. At the same time, the blown gas has a drying effect on the surface of the granulation strip, effectively removing surface moisture, saving the need for a dryer, reducing energy consumption, and saving floor space.

[0023] In this utility model, the bracket is provided with multiple adjustment holes from top to bottom. The two ends of the intermediate shaft pass through the corresponding adjustment holes of two brackets respectively and are fixed by nuts.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings:

[0030] This utility model embodiment provides a cold-cut granulation strip support roller, such as... Figure 1 As shown, it includes a base 1, on which two supports 2 are arranged opposite each other, and a roller 3 is arranged between the two supports 2;

[0031] like Figure 2 As shown, the idler roller 3 includes an intermediate shaft and multiple baffles disposed on the intermediate shaft. The intermediate shaft is a hollow structure, with one end closed and the other end provided with an air inlet valve 5. An air outlet 4 is disposed on the intermediate shaft at a position between two adjacent baffles.

[0032] In use, compressed gas is supplied by an air pump. The compressed gas enters the intermediate shaft of the idler roller through the air inlet valve 5 and is ejected from the air outlet 4 between two adjacent baffles, achieving an upward blowing effect. When the material strip passes between two adjacent baffles, the gas ejected from the air outlet 4 has an upward blowing force, which reduces the friction between the material strip and the idler roller. At the same time, the blown gas has a drying effect on the surface of the material strip, which can effectively remove the moisture on the surface of the material strip, save the need for a dryer, and reduce energy consumption and save space.

[0033] In a preferred embodiment of this utility model, the air outlet 4 is located at the top of the intermediate shaft. During the process of traction of the material strip, the gas sprayed through the air outlet 4 can have an upward blowing force on the material strip, which reduces the friction between the material strip and the roller. At the same time, the blown gas has a drying effect on the surface of the material strip, which can effectively remove the moisture on the surface of the material strip, save the need for a dryer, and reduce energy consumption and save space.

[0034] As a preferred embodiment of this utility model, such as Figure 3As shown, the support 2 is provided with multiple adjustment holes 6 from top to bottom. Preferably, the support 2 is provided with three adjustment holes 6 from top to bottom. The two ends of the intermediate shaft pass through the corresponding adjustment holes 6 of the two supports 2 respectively and are fixed by nuts to realize the adjustment of the height of the roller 3. The position of the roller 3 on the support 2 can be adjusted according to the required height, which is convenient, practical and efficient. After the position of the roller 3 is fixed, the air inlet valve 5 is connected to the air pump to introduce compressed air, and the air outlet 4 starts to spray gas, which guides the material strip through the roller 3 to the pelletizer to start pelletizing. In this process, the gas provides an upward blowing force to reduce the friction between the roller and the material strip, and can also effectively remove the moisture on the surface of the strip, saving the air dryer, reducing energy consumption and saving space.

[0035] In a preferred embodiment of this utility model, multiple baffles are evenly arranged axially on the intermediate shaft, so that the gas ejected through the air outlet 4 can effectively remove moisture from the surface of the material strip while reducing the friction between the roller and the material strip, thus reducing energy consumption.

[0036] In a preferred embodiment of this utility model, the idler roller 3 is a stainless steel idler roller, which can avoid rust corrosion and has a certain strength to make the structure more stable. Preferably, the idler roller is a one-piece molded structure.

[0037] When using the cold-cut granulation strip roller provided by this utility model to pull the material strip, firstly, according to the required height, the two ends of the intermediate shaft are respectively passed through the opposite adjustment holes 6 of the two brackets 2 and fixed with nuts. The air pump is connected to the air inlet valve 5, and compressed gas is provided by the air pump. The compressed gas enters the intermediate shaft of the roller 3 through the air inlet valve 5 and is sprayed out from the air outlet 4 between two adjacent baffles to achieve an upward blowing effect. When the strip passes through the middle of the two adjacent baffles, the gas sprayed from the air outlet 4 has an upward blowing force, which reduces the friction between the strip and the roller. At the same time, the blown gas has a drying effect on the surface of the strip, which can effectively remove the moisture on the surface of the strip, save the need for a dryer, reduce energy consumption, and save space.
