Description

Technical Field

[0001] This utility model relates to the field of cooling and shaping, and in particular to a cooling and shaping device for PE pipes. Background Technology

[0002] PE pipes are made from polyethylene resin as the main raw material through an extrusion molding process. Polyethylene is a high-molecular polymer, which endows PE pipes with many excellent properties, such as strong corrosion resistance, resisting the erosion of various chemicals; good low-temperature resistance, maintaining good performance in cold environments; good flexibility, adapting to a certain degree of bending and deformation; and high chemical stability, not easily undergoing chemical reactions. PE pipes are hygienic and non-toxic, meeting hygiene standards and suitable for drinking water transportation.

[0003] During the production of PE pipes, although the extruder die provides initial shape constraints, the freshly extruded pipe is in a high-temperature, viscous flow state, exhibiting significant plasticity and unstable shape. Without cooling and setting, the pipe is easily deformed under its own weight and external forces, compromising dimensional accuracy and appearance quality. Cooling and setting allows for rapid cooling and solidification, fixing the pipe's shape and ensuring it meets the required dimensional specifications and surface quality, thus satisfying various performance requirements in practical applications.

[0004] In related technology, application number CN202323562119.1 discloses a PE pipe shaping and cooling device. By activating pump two, the cooled water, after being filtered to remove impurities, is transported to a water storage tank through return pipe one and return pipe two, thus recycling the cooling water and avoiding water waste. However, during use, because the water tank is fixed to the frame, it is inconvenient to clean the impurities inside the tank. The repeatedly recycled cooling water will contain impurities, which, if accumulated in the tank over a long period, are not only difficult to clean but may also clog the filter screen, thereby affecting the operation of the water pump.

[0005] Therefore, it is necessary to provide a PE pipe cooling and shaping device to solve the above-mentioned technical problems. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 A PE pipe cooling and shaping device includes: a cooling platform 1, and a cooling component 2 is provided at the bottom of the cooling platform 1;

[0023] The cooling assembly 2 includes a support frame 21 located at the bottom of the cooling platform 1. A guide rail 22 is provided on the top of the support frame 21. A water tank body 23 is slidably mounted on the top of the guide rail 22. A cooling rack 24 is fixedly mounted on the back of the water tank body 23. A water pipe 25 is provided on the left side of the front of the cooling rack 24. An annular spray pipe 26 is provided at the front end of the water pipe 25.

[0024] By configuring the water tank body 23, the cooling water sprayed from the annular spray pipe 26 flows back into the water tank body 23. By configuring the water pump 28, the cooling water is sprayed out again from the annular spray pipe 26 through the water pipe 25, thus realizing the recycling of cooling water.

[0025] A partition plate 27 is vertically arranged on the inner side of the water tank body 23. A water pump 28 is arranged at the bottom of the inner wall of the water tank body 23 and on the right side of the partition plate 27. The outlet of the water pump 28 is connected to the bottom end of the water pipe 25. A cooling pipe 29 is arranged on the periphery of the water pipe 25 and inside the cooling rack 24.

[0026] Cooling pipe 29 is used to cool water pipe 25, so that the water temperature is reduced when it flows through, thereby achieving the purpose of cooling and shaping PE pipe.

[0027] A filter screen 3 is provided on the inner wall of the water tank body 23 and on the left side of the partition plate 27. A rotating screw 4 is provided on the inner wall of the water tank body 23 and on the left side of the filter screen 3 in a longitudinal direction and is rotatable. The front end of the rotating screw 4 passes through the inner wall of the water tank body 23 and extends to its front.

[0028] The rotation of the lead screw 4 drives the movement of the cleaning brush 5. When the water tank body 23 is pulled outward, the gear 7 will rotate to one side under the action of the rack frame 6, which will drive the cleaning brush 5 to move forward. During the forward movement, the cleaning brush 5 can brush off the impurities attached to the surface of the filter screen 3, thereby reducing the cleaning work on the surface of the filter screen 3 when the water tank body 23 is pulled out for cleaning.

[0029] A cleaning brush 5 is provided on the inner side of the water tank body 23 and on the left side of the filter screen 3, and can slide back and forth. The circumferential side of the rotating screw 4 is threadedly connected to the top of the cleaning brush 5, and the right side of the cleaning brush 5 is attached to the left side of the filter screen 3.

[0030] A rack frame 6 is provided on the front side of the top of the support frame 21, and a gear 7 is provided at the front end of the rotating screw 4. The bottom of the gear 7 meshes with the top of the rack frame 6. A positioning block 8 is provided on the right side of the water tank body 23.

[0031] By setting the positioning block 8, it is possible to prevent the water tank body 23 from sliding after it enters the inner side of the support frame 21.

[0032] A water filter block 9 is provided on the right side of the front of the cooling rack 24, and a water guide plate 10 is provided on the top of the cooling platform 1 and below the water filter block 9.

[0033] The inner diameter of the filter block 9 is similar to the outer diameter of the PE pipe. When the PE pipe passes through the inside of the filter block 9, the water on its surface will be wiped off by the filter block 9 and fall off, and then flow back into the interior of the water tank body 23 under the action of the water guide plate 10.

[0034] The working principle of the PE pipe cooling and shaping device provided by this utility model is as follows:

[0035] Step 1: During use, after the PE pipe is extruded by the extrusion device, one end of it passes through the inside of the annular spray pipe 26 and the filter block 9. The cooling water filtered inside the water tank body 23 is driven by the operation of the water pump 28 and discharged through the water pipe 25. During this process, the cooling water can be cooled by the setting of the cooling pipe 29 and finally sprayed out through the annular spray pipe 26, so that the PE pipe can be cooled and shaped.

[0036] Step 2: After a period of use, there are many impurities inside the water tank body 23. You can pull the positioning block 8 upward to make the water tank body 23 disengage from the support frame 21, and push the water tank body 23 to the right to disengage the water tank body 23 from the cooling platform 1, so that the impurities inside the water tank body 23 can be easily cleaned.

[0037] Step 3: During the process of separating the water tank body 23 from the support frame 21, under the action of the rack frame 6, the gear 7 rotates and drives the rotating screw 4 to rotate, which in turn drives the cleaning brush 5 to slide forward in the direction of the rotating screw 4. Thus, the right side of the cleaning brush 5 cleans the left side of the filter screen 3, reducing the time for subsequent separate cleaning of the filter screen 3 and improving cleaning efficiency. At the same time, during the process of installing the water tank body 23 onto the support frame 21, the cleaning brush 5 will move backward and reset.

[0038] Compared with related technologies, the PE pipe cooling and shaping device provided by this utility model has the following beneficial effects:

[0039] By pulling the positioning block 8 upwards, the water tank body 23 is disengaged from the support frame 21, making it easier to clean the impurities inside the water tank body 23. Under the action of the rack frame 6, the gear 7 rotates, driving the rotating screw 4 to rotate, which in turn drives the cleaning brush 5 to slide forward in the direction of the rotating screw 4. Thus, the right side of the cleaning brush 5 cleans the left side of the filter screen 3, reducing the time required for subsequent separate cleaning of the filter screen 3 and improving cleaning efficiency.

[0040] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
