Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic pipe extrusion water cooling, especially relates to a transparent plastic pipe water cooling mechanism after extrusion. BACKGROUND

[0002] Transparent plastic pipe extrusion is a plastic forming process, mainly used for producing transparent or translucent plastic pipes. Transparent plastic pipes are divided into single-extruded pipe materials and composite pipe materials. The production process of single-extruded plastic pipes is relatively simple, mainly according to the product's mouth shape, the material in the screw cylinder is extruded through the mouth shape to complete the forming production. The production process of composite plastic pipes is more complex, some plastic pipes have braided wires in the middle, and some have steel wires. These products with special structures need to choose appropriate production equipment and production methods according to specific needs.

[0003] At present, the transparent plastic pipe water cooling mechanism after extrusion generally uses the spraying method to realize water cooling operation, but this method has some obvious shortcomings in actual use. Especially in the conveying process of the conveying pipe, due to the limitations of the spraying system, some areas often cannot be fully sprayed.

[0004] This uneven spraying phenomenon leads to temperature difference in different areas of the pipe. Some areas may be over-cooled due to excessive spraying, while other areas may not be cooled enough due to insufficient spraying. This temperature difference not only affects the cooling effect, but also may cause deformation, shrinkage or surface defects of the plastic pipe during the cooling process. UTILITY MODEL CONTENTS

The inside of the water cooling box 1 is specially designed with two partitions, and the partitions divide the inner cavity of the water cooling box 1 into two parts of the water cooling bin 2 and the overflow bin 6, wherein the overflow bin 6 is carefully arranged on both sides of the water cooling bin 2;

[0026] In the inside of the water cooling bin 2, the first fixed conveying frame 3 and the second fixed conveying frame 4 are arranged, and the two conveying frames are designed in an "X" shape, so that the transparent plastic pipe can smoothly pass through. In addition, the driving device 5 is installed on the second fixed conveying frame 4, and through the driving action of the driving device 5, the second fixed conveying frame 4 can be driven to move correspondingly, so as to realize the conveying process of the transparent plastic pipe;

[0027] The second pipe 10 is connected with the first pipe 8 through the circulating pump 9, and the fourth pipe 12 is connected with the third pipe 11 through the valve 13. The first pipe 8 and the third pipe 11 are connected with the water tank 7 respectively. Through the joint action of the circulating pump 9, the pipes and the water tank 7, the circulation operation of the cooling water in the water cooling bin 2 can be realized, so that the transparent plastic pipe can be effectively cooled after being extruded.

[0028] The first fixed conveying frame 3 and the second fixed conveying frame 4 both include side frames, rollers and bearing assemblies. The rollers are installed on the two side frames through the bearing assemblies to ensure their stability and durability. The lowermost side frame is fixed on the water cooling tank 1 through a support and bolts to ensure the stability of the whole conveying frame. The upper end of the second fixed conveying frame 4 is also provided with a chain. The output end of the driving device 5 is connected with the chain through a gear, and the roller is driven to move through this way, so that the driving of the conveying frame is realized.

[0029] The upper end of the water cooling tank 1 is provided with an inlet and an outlet, which are opposite to the feeding bins of the first fixed conveying frame 3 and the second fixed conveying frame 4, so as to facilitate the feeding and discharging of the transparent plastic pipe.

[0030] The connection between the second pipe 10 and the fourth pipe 12 and the water cooling tank 1 is sealed. They are arranged in a low-high position, which is designed to facilitate the feeding and discharging of the water cooling bin 2.

[0031] The connection between the first pipe 8 and the third pipe 11 and the water tank 7 is also sealed. The upper end of the water tank 7 is provided with a sealing cover to prevent the leakage of the cooling water. The water tank 7 is also provided with a filter screen cylinder, through which the filtering operation of the circulating cooling water can be realized, so as to ensure the cleanliness of the cooling water and improve the cooling effect of the transparent plastic pipe.

[0032] The cooling water in the water cooling bin 2 flows into the water tank 7 from the first pipe 8 and the second pipe 10, is filtered and cooled, and then flows into the water cooling bin 2 from the third pipe 11 and the fourth pipe 12, forming an effective cooling circulation system.

[0033] Assembly process: Install two partitions inside the water-cooled box 1 to divide the inner cavity into a water-cooled compartment 2 and a water overflow compartment 6. Install the first fixed conveying frame 3 and the second fixed conveying frame 4 inside the water-cooled box 1, ensuring they are arranged in an "X" shape. Install the driving device 5 on the second fixed conveying frame 4. Connect the second pipe 10 to the first pipe 8 through the circulating pump 9. Connect the fourth pipe 12 to the third pipe 11 through the valve 13. Connect the first pipe 8 and the third pipe 11 to the water tank 7 respectively. Ensure that all pipe connections are sealed well. Fix the water tank 7 in place, ensuring that the upper end seal cover is installed in place. Install the filter screen cylinder in the water tank 7. Fix the side frames of the first fixed conveying frame 3 and the second fixed conveying frame 4 to the water-cooled box 1 through supports and bolts. Connect the output end of the driving device 5 to the chain on the second fixed conveying frame 4 through a gear. Open the feed inlet and discharge outlet at the upper end of the water-cooled box 1, ensuring they are directly opposite the conveying frame's feeding compartment. Check the tightness of all connections to ensure there is no leakage. Ensure that the second pipe 10 and the fourth pipe 12 are connected to the water-cooled box 1 at different heights to facilitate water inlet and outlet operations.

[0034] Usage: Open the seal cover of the water tank 7 and add an appropriate amount of cooling water. Start the circulating pump 9 to ensure that the cooling water circulation system starts to work. Place the transparent plastic pipe from the feed inlet into the water-cooled box 1, making it pass through the first fixed conveying frame 3 and the second fixed conveying frame 4. Start the driving device 5 to move the second fixed conveying frame 4, realizing the conveying of the transparent plastic pipe. When the transparent plastic pipe passes through the water-cooled compartment 2, cooling water flows in from the first pipe 8 and the second pipe 10, and after passing through the water-cooled compartment 2, it flows back to the water tank 7 from the third pipe 11 and the fourth pipe 12. The cooling water is filtered and cooled in the water tank 7 and then flows into the water-cooled compartment 2 again, forming an effective cooling circulation system. Monitor the temperature and flow of the cooling water to ensure that the transparent plastic pipe is fully cooled. Adjust the speed of the driving device 5 as needed to control the conveying speed of the transparent plastic pipe. The transparent plastic pipe is discharged from the discharge outlet after cooling, completing the entire cooling process. Regularly check the cleanliness of the cooling water and replace the filter screen cylinder if necessary. Check the tightness of all connections to ensure there is no leakage. Regularly maintain and check the driving device 5 and other mechanical parts to ensure normal operation of the equipment.
