Description

Technical Field

[0001] This utility model relates to the field of plastic production technology, specifically to a cooling mechanism for plastic extrusion strips. Background Technology

[0002] The extrusion method in plastic extruders generally refers to melting plastic at a high temperature of around 200 degrees Celsius, and then extruding the molten plastic through a die to form the final shape. This method, also known as "extrusion molding," involves heating and pressurizing the material in an extruder to continuously pass it through a die in a flowing state. Compared to other molding methods, it has the advantages of high efficiency and low unit cost. Extrusion is mainly used for molding thermoplastics, but can also be used for some thermosetting plastics. Existing plastic extrusion strips require cooling and further processing.

[0003] Existing plastic extrusion strip cooling mechanisms have the following drawbacks during use: generally, the extruded plastic strip is cooled by circulating cold water tank, but the cooling tank uses a large amount of water, and the cooling effect is poor after the water temperature rises. Therefore, this application proposes a plastic extrusion strip cooling mechanism to solve the above problems. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows: a cooling mechanism for plastic extrusion strips, comprising: a main body and a cooling mechanism, wherein the main body includes multiple legs, multiple cooling pipes fixed in an array on the legs, a water inlet fixed at one end of the cooling pipes, and a water collection shell fixed at the other end of the cooling pipes.

[0006] The cooling mechanism includes a box body located on one side of the support leg, multiple honeycomb filler layers fixed on the inner wall of the box body, a spray element fixed on the box body and extending into the inner cavity of the box body, a first pump fixed on the outer side of the box body with one end connected to the water collection shell and the other end connected to the spray element, air inlet pipes symmetrically installed on both sides of the box body, a high-speed fan fixed on the inner wall of the box body, and a second pump installed on the outer side of the box body with one end connected to the inner cavity of the box body and the other end connected to the water inlet element.

[0007] In a preferred embodiment, the present invention can be further configured such that: the cooling pipe includes a pipe body fixed to the top of the support leg and baffles symmetrically fixed to the pipe body, and the top of the pipe body is open.

[0008] In a preferred embodiment, the present invention can be further configured such that the water inlet includes a first hollow pipe disposed on one side of the end of the pipe body and a plurality of pipe heads fixed on the first hollow pipe and extending into the inner cavity of the pipe body.

[0009] In a preferred embodiment, the present invention can be further configured such that: the water inlet of the first pump is connected to the inner cavity of the water collection shell through the first water inlet pipe, and the water outlet of the first pump is connected to the spraying component through the first water outlet pipe.

[0010] In a preferred embodiment, the present invention can be further configured such that the spraying component includes a rectangular hollow pipe fixed on the outer side of the box, a plurality of branch pipes fixed on the rectangular hollow pipe and extending into the inner cavity of the box, and a plurality of spray nozzles fixed on the branch pipes.

[0011] In a preferred embodiment, the present invention can be further configured such that: the water inlet of the second pump is connected to the bottom of the inner cavity of the tank through the second water inlet pipe, and the water outlet of the second pump is connected to the water inlet component through the second water outlet pipe.

[0012] In a preferred embodiment, the present invention can be further configured such that a filter screen is fixed on the inner wall of the air inlet pipe.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. In this utility model, multiple support legs are provided, and multiple cooling pipes are arranged in an array on the support legs. A water inlet is provided at one end of the cooling pipe, and a water collection shell is provided at the other end. After the plastic strip is extruded by the extruder, it directly enters the cooling pipe. Cooling water is sent into the cooling pipe through the water inlet and flows in the cooling pipe, carrying away the heat on the plastic strip and cooling the plastic strip. Through the above arrangement, while ensuring the cooling effect of the plastic strip, the amount of cooling water used is reduced, thereby reducing the cooling cost and increasing the practical performance.

[0014] 2. In this utility model, a box body is provided, and a honeycomb filling layer is provided in the inner cavity of the box body. A spray element extending into the box body is provided on one side of the box body, and a high-speed fan is installed at the bottom of the inner cavity of the box body. A first pump is also provided, with one end connected to a water collection shell and the other end connected to the spray element. A second pump is provided, with one end connected to a water inlet and the other end connected to the bottom of the inner cavity of the box body. Through the above arrangement, the cooling water that has absorbed heat enters the water collection shell. Subsequently, the first pump extracts the water from the water collection shell and pumps it into the spray element, which then sprays the water downwards. The water flows into the honeycomb filling layer, while a high-speed fan starts to expel air from the chamber. Outside air enters the chamber through the air inlet pipe, creating a high-speed airflow from bottom to top. The high-speed airflow passes through the filling layer, comes into contact with the water, exchanges heat, and carries away heat to cool the water. The cooled water falls to the bottom of the chamber and is then pumped back into the water inlet by the second pump, forming a circulation. This ensures a stable cooling water temperature in the cooling pipes and prevents the cooling water temperature from being too high, which could affect the cooling effect of the plastic strips, further increasing its practicality.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0018] Some embodiments of this utility model are described below with reference to the accompanying drawings. Example

[0019] Combination Figure 1-4 As shown, this embodiment provides a cooling mechanism for plastic extrusion strips, including: a main body 100 and a cooling mechanism 200.

[0020] The main body 100 includes multiple legs 110, multiple cooling pipes 120 fixed in an array on the legs 110, a water inlet 130 fixed at one end of the cooling pipe 120, and a water collection shell 140 fixed at the other end of the cooling pipe 120.

[0021] The support leg 110 is used to install the cooling pipe 120 to ensure the stability of the cooling pipe 120. The cooling pipe 120 is used to cool the plastic strip, reduce the cooling space, and reduce the amount of cooling water. The cooling pipe 120 includes a pipe body 121 fixed to the top of the support leg 110 and baffles 122 symmetrically fixed on the pipe body 121. The top of the pipe body 121 is open for inserting the plastic strip. Only one plastic strip can be inserted into each cooling pipe 120 to avoid multiple plastic strips from tangling together. The baffles 122 are used to prevent the cooling water in the pipe body 121 from flowing out.

[0022] The water inlet 130 is used to send cooling water into the cooling pipe 120. It includes a first empty pipe 132 disposed on one side of the end of the pipe body 121 and a plurality of pipe heads 131 fixed on the first empty pipe 132 and extending into the inner cavity of the pipe body 121. The cooling water enters the first empty pipe 132 and enters the pipe heads 131 evenly through the first empty pipe 132. Then it enters the cooling pipe 120 through the pipe heads 131 and flows in the cooling pipe 120, exchanges heat with the plastic strip, takes away the heat on the plastic strip, and cools the plastic strip.

[0023] The water collection shell 140 is fixed to the other end of the cooling pipe 120 and is used to collect the cooling water that has absorbed heat inside the cooling pipe 120.

[0024] The cooling mechanism 200 is used to cool the cooling water after absorbing heat to prevent the cooling water temperature from becoming too high. It includes a housing 210 set on one side of the support leg 110, multiple honeycomb filler layers 220 fixed on the inner wall of the housing 210, a spray element 240 fixed on the housing 210 and extending into the inner cavity of the housing 210, a first pump 230 fixed on the outer surface of the housing 210 with one end connected to the water collection shell 140 and the other end connected to the spray element 240, air inlet pipes 250 symmetrically installed on both sides of the housing 210, a high-speed fan 260 fixed on the inner wall of the housing 210, and a second pump 270 installed on the outer surface of the housing 210 with one end connected to the inner cavity of the housing 210 and the other end connected to the water inlet element 130.

[0025] The housing 210 is used to install other components. The honeycomb filler layer 220 can effectively increase the contact area between water and air. When water falls into the honeycomb filler layer 220, it can adhere to the surface of the honeycomb filler layer 220 to form a water film, which greatly increases the heat exchange contact area with air. When air passes through, it can quickly take away the heat in the water and cool the water.

[0026] The spray element 240 is used to spray water evenly into the honeycomb filler layer 220. It includes a rectangular hollow pipe 241 fixed on the outer side of the box 210, multiple branch pipes 242 fixed on the rectangular hollow pipe 241 and extending into the inner cavity of the box 210, and multiple nozzles 243 fixed on the branch pipes 242. At the same time, the inlet of the first pump 230 is connected to the inner cavity of the water collection shell 140 through the first inlet pipe 232, and the outlet of the first pump 230 is connected to the rectangular hollow pipe 241 through the first outlet pipe 231. With this configuration, the first pump 230 is started, and water is drawn out of the water collection shell 140 through the first inlet pipe 232 and sent into the spray element 240 through the first outlet pipe 231. The water that has absorbed heat is sprayed downward evenly through the spray element 240 to form water droplets, which fall evenly into the honeycomb filler layer 220.

[0027] The air inlet duct 250 is located on both sides of the housing 210 and below the honeycomb filling layer 220, facilitating the entry of outside air into the inner cavity of the housing 210. The high-speed fan 260 is positioned upwards. When the high-speed fan 260 rotates, it exhausts the hot air inside the housing 210, while outside cold air enters the inner cavity of the housing 210 through the air inlet, forming an upward airflow inside the housing 210. The high-speed airflow passes through the filling layer, which can quickly remove the heat from the water film and cool the water. In addition, a filter screen is installed on the inner wall of the air inlet duct 250 to filter dust in the air and prevent dust from entering the housing 210 and mixing into the water, thus contaminating the cooling water.

[0028] The inlet of the second pump 270 is connected to the bottom of the inner cavity of the housing 210 through the second inlet pipe 272, and the outlet of the second pump 270 is connected to the inlet component 130 through the second outlet pipe 271. When the second pump 270 is started, it draws out the cooled water from the bottom of the inner cavity of the housing 210 through the second inlet pipe 272 and pumps it into the inlet component 130 through the second outlet pipe 271, forming a circulation of cooling water.

[0029] The working principle and usage process of this utility model are as follows: During use, the plastic strip extruded by the extruder is placed into the cooling pipe 120. At this time, the second pump 270 starts, drawing cooling water from the bottom of the inner cavity of the housing 210 through the second inlet pipe 272 and pumping it into the inlet component 130 through the second outlet pipe 271. The cooling water is then sent into the cooling pipe 120 through the inlet component 130 and flows within the cooling pipe 120, exchanging heat with the plastic strip to remove heat and cool it. The cooled water, having absorbed heat, enters the water collection shell 140. Then, the first pump 230 starts, drawing water from the water collection shell 140 through the first inlet pipe 232. Water is extracted from the container and sent to the spray element 240 through the first water outlet pipe 231. The water that has absorbed heat is sprayed downwards evenly through the spray element 240, forming water droplets that fall evenly into the honeycomb packing layer 220. At the same time, the high-speed fan 260 is started to exhaust the air inside the box 210. Outside air enters the box 210 through the air inlet pipe 250, forming a high-speed airflow from bottom to top inside the box 210. The high-speed airflow passes through the packing layer, comes into contact with the water, exchanges heat, carries away heat, and cools the water. The cooled water falls to the bottom of the box 210 and is then pumped back into the water inlet 130 by the second pump 270, forming a circulation.
