Description

Technical Field

[0001] This utility model relates to the field of barrel screw technology, and specifically to a high-efficiency barrel screw. Background Technology

[0002] The barrel and screw are crucial components of an extruder. The barrel and screw work together, with the barrel containing the screw, which rotates inside. As the screw rotates, it propels the plastic forward within the barrel. Heat is transferred from the outside of the barrel to the plastic inside. Furthermore, the gradually decreasing volume of the screw's threads causes the plastic within the threaded grooves to be subjected to various forces such as compression, tumbling, and shearing, resulting in uniform mixing and plasticizing. As the plastic moves towards the front of the barrel, it gradually melts into a viscous flow state, completing the plasticization process. The proper coordination between the barrel and screw ensures continuous extrusion production of raw materials.

[0003] The barrel and screw generate a lot of heat during plastic processing. In order not to affect the plasticizing and injection process, they need to be cooled. However, most existing cooling methods are to blow air to dissipate heat. However, a single cooling method is slow and has a poor cooling effect, which cannot meet the cooling needs of customers.

[0004] Therefore, those skilled in the art have provided a high-efficiency barrel screw to solve the problems mentioned in the background art. Utility Model Content

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0032] In the embodiments, such as Figure 1 , Figure 2 , Figure 3 As shown, a high-efficiency barrel screw includes a barrel 1, and further includes:

[0033] Cooling box 2 is installed on the outer surface of the barrel 1;

[0034] Cooling pipe 3 is installed inside cooling box 2 and spirally arranged on the outer surface of barrel 1;

[0035] Submersible pump 4 is installed inside cooling tank 2.

[0036] Drain pipe 5, one end is connected to submersible pump 5, and the other end is connected to cooling pipe 3;

[0037] Spray pipe 6 is installed inside cooling box 2, and spray nozzles 7 are evenly distributed on spray pipe 6;

[0038] One end of the water inlet pipe 8 is connected to the spray pipe 6, and the other end is connected to the other end of the cooling pipe 3;

[0039] Cover plate 9 is located on top of cooling box 2;

[0040] The blower assembly 10 is mounted on the cover plate 9;

[0041] The positioning cylinder 11 is embedded in the top of the cover plate 9. The inner cavity of the positioning cylinder 11 is filled with a sponge 12, and the bottom of the positioning cylinder 11 is provided with an air outlet 13.

[0042] The cooling tank 2, cooling pipe 3, submersible pump 4, drain pipe 5, spray pipe 6, nozzle 7 and water inlet pipe 8 are designed to facilitate heat dissipation by conducting water spray on the barrel 1. The cover plate 9 and the air blowing assembly 10 are designed to conduct air cooling on the barrel 1 and cooling pipe 3, as well as the cooling water, preventing the cooling water from conducting heat. The positioning cylinder 11, sponge 12 and air outlet 13 are designed to facilitate air circulation in the interior of the cooling tank 1, while preventing water molecules from condensing and flowing back into the tank.

[0043] In the embodiments, such as Figure 2 , Figure 4 As shown, the air blowing assembly 10 includes an air box 101, which is embedded in the connection between the air box 101 and the cover plate 9. A fan 102 is fixedly installed on the top of the inner cavity of the air box 101, and filters 103 are embedded on both the left and right sides of the top of the air box 101. The air box 101, fan 102, and filters 103 can conveniently blow air to dissipate heat from the barrel and cooling pipes, as well as to dissipate heat from the cooling water, avoiding heat conduction by the cooling water.

[0044] In the embodiments, such as Figure 3 , Figure 4 As shown, a filter cover 14 is threadedly connected to the top of the positioning cylinder 11, and a transparent observation window is embedded in the bottom of the front side of the cooling box 2. The filter cover 14 facilitates air circulation inside the positioning cylinder 11, and the transparent observation window allows staff to easily check the level of cooling water inside the cooling box.

[0045] In the embodiments, such as Figure 1 , Figure 2 As shown, the cover plate 9 and the cooling box 2 are fixedly installed together by screws, and the right side of the top of the barrel 1 is connected to the feed funnel 15. The feed funnel 15 is provided to facilitate the entry of materials into the inner cavity of the barrel 1.

[0046] In the embodiments, such as Figure 2As shown, the spray pipe 6 is located below the barrel 1, and brackets 16 are fixedly connected to both the left and right sides of the bottom of the spray pipe 6. The bottom of the brackets 16 is fixedly connected to the connection point of the cooling box 2. The brackets 16 facilitate the support and installation of the spray pipe 6.

[0047] In the embodiments, such as Figure 2 As shown, a water inlet pipe is connected to the left side of the cooling tank 2 and below the barrel 1, and one end of the water inlet pipe is threaded with a pipe cap. This facilitates the addition of cooling water to the inner cavity of the cooling tank.

[0048] In the embodiments, such as Figure 2 As shown, a water outlet pipe is connected to the bottom right side of the cooling tank 2, and a sealing cap is threaded to one end of the water outlet pipe. The water outlet pipe and the sealing cap facilitate the cleaning and drainage of cooling water inside the cooling tank.

[0049] The implementation principle of this utility model is as follows: During use, when the barrel 1 generates heat during operation, the operator plugs in the submersible pump 4 and fan 102, activating the external controllers of the submersible pump 4 and fan 102. This causes the submersible pump 4 to draw cooling water from the inner cavity of the cooling tank 2 and deliver it to the inner cavity of the cooling pipe 3. The combined use of the cooling pipe 3 and the flowing cooling water in the inner cavity cools and dissipates heat from the barrel 1. Simultaneously, the flowing cooling water enters the inner cavity of the spray pipe 6, causing the spray pipe 6 to spray water onto the outer surface of the barrel 1 and the cooling pipe 3 through the nozzles 7, achieving water spray cooling of the barrel 1 and further enhancing the cooling effect. At the same time... The fan 102 rotates and blows air onto the barrel 1, which, together with the sprayed cooling water, further accelerates the heat dissipation of the barrel 1, thereby achieving multi-mode cooling and heat dissipation of the barrel 1 and enabling rapid heat dissipation. At the same time, the air inside the cooling box 2 is discharged through the air outlet 13, the positioning cylinder 11 and the filter cover 14. When the air is discharged, the sponge 12 blocks and filters the water molecules in the flowing air, causing the water molecules to condense into water droplets and flow back into the cooling box 2, thereby realizing the recycling of water resources. This device is simple to operate and convenient for multi-mode cooling and heat dissipation, thus meeting the needs of customers.

[0050] Obviously, the above embodiments of this utility model are merely illustrative examples and not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
