Description

Technical Field

[0001] The utility model relates to the technical field of polyethylene pipes, and more specifically, to a polyethylene pipe extrusion device. Background Art

[0002] Polyethylene pipe (PE pipe) is a pipe made of polyethylene material, and its English name is Polyethylene. This kind of pipe has a wide range of applications in my country, among which water supply pipes and gas pipes are its two largest application markets.

[0003] When a general polyethylene pipe extrusion device is in use, the material is first passed through the feed port into the interior of the forming cylinder, and then the polyethylene pipe is formed through the cooling cylinder inside the forming cylinder. When the material enters below the feeding port, the material is passed through the feeding port into the interior of the forming cylinder to fill the holes above the polyethylene pipe to be formed, and then the formed polyethylene pipe is extruded through the internal extrusion mechanism. However, the extruded formed pipe is fixed in the cooling pipe by the internal coolant for cooling. After a long time of use, the coolant may overheat. In order to continue to have a good cooling effect, the coolant must be replaced, which will result in low efficiency, so it needs to be modified and optimized. Utility Model Content

[0028] A cooling mechanism is rotatably disposed on one side of the housing 5;

[0029] The cooling mechanism includes a large gear 10 fixedly arranged on one side of the shell 5, a fixed plate 8 is fixedly installed on the side of the large gear 10, a water pipe 7 is fixedly installed above the fixed plate 8, the water pipe 7 movably passes through the upper and lower sides of the fixed plate 8 and is fixedly installed with a nozzle 9, a cooling box 6 is fixedly installed on the other end of the water pipe 7, the cooling box 6 is fixedly arranged above the shell 5, a motor 12 is fixedly installed on the side of the shell 5, a pinion 11 is fixedly installed above the transmission shaft of the motor 12, and the pinion 11 and the large gear 10 are meshed with each other, a motor 2 14 is fixedly installed on the other side of the shell 5, a pinion 2 13 is fixedly installed above the transmission shaft of the motor 2 14, and the pinion 2 13 and the large gear 10 are meshed with each other.

[0030] When the staff uses the device, the extruded polyethylene tube needs to be cooled. First, by starting the motor 2 14 and the motor 1 12, and then starting the nozzle 9, the motor 2 14 and the motor 1 12 drive the pinion 2 13 and the pinion 1 11 to rotate in opposite directions. When the pinion 2 13 is meshed with the large gear 10, the large gear 10 will be driven to rotate. When the pinion 11 and the large gear 10 are meshed with each other, the large gear 10 will be driven to rotate. As the pinion 11 and the pinion 2 13 drive the large gear 10 to rotate at different time periods respectively, the nozzle 9 makes a semi-circular motion above the extrusion groove 19, and the liquid inside the cooling box 6 enters the interior of the nozzle 9 through the water pipe 7 and is sprayed out.

[0031] By starting motor 2 14 and motor 1 12, and then starting nozzle 9, when small gear 2 13 is meshed with large gear 10, it will drive large gear 10 to rotate, and when small gear 11 is meshed with large gear 10, it will drive large gear 10 to rotate, and the liquid inside cooling box 6 will be sprayed out through nozzle 9 to cool the extruded polyethylene tube. Compared with the traditional device, this device sprays water into the extruded polyethylene tube through nozzle 9 to cool it, thereby reducing the temperature of the extruded polyethylene tube, facilitating the processing of the extruded polyethylene tube, and improving the working efficiency of the device.

[0034] When the device is started, due to its large weight, the entire device will vibrate. When the device vibrates, it will drive the shell 5 to move downward and upward. When the shell 5 moves downward, it will drive the top of the damper 4 to move downward. When the top of the damper 4 moves downward, the top of the spring 3 will shrink downward. When the damper 4 and the top of the spring 3 are compressed downward, the shell 5 will move as the top of the spring 3 and the damper 4 move downward. When the spring 3 and the damper 4 are compressed to the extreme, the spring 3 and the damper 4 will drive the shell 5 to move upward.

[0035] After starting the device, the entire device vibrates. When the device vibrates, it drives the shell 5 to move downward and upward. When the top of the damper 4 moves downward, the top of the spring 3 contracts downward, thereby reducing the shock of the entire device. Compared with traditional devices, this device can reduce the vibration generated by the device through the cooperation between the spring 3 and the damper 4 in the shock absorbing mechanism, reduce the impact of the vibration on the internal parts of the device, reduce the wear between the internal parts of the device, and reduce the use cost of the device.

[0037] The internal material is thermoformed and extruded into the shape of a pipe, which improves the working efficiency of the device.

[0038] It also includes a fixed block 20 fixedly arranged inside the extrusion groove 19, and a cooling pipe 17 is fixedly installed inside the fixed block 20. The cooling pipe 17 is fixedly passed through the left and right sides of the fixed block 20, and a water pumping pipe 18 is movably installed inside the cooling pipe 17.

[0039] By placing a coolant inside the cooling tube 17 , the internal polyethylene tube can be quickly formed, and the internal coolant can be pumped out through the pumping tube 18 .

[0040] There are six groups of shock absorbing mechanisms in total, which are evenly distributed above the shock absorbing base 2 and are all fixedly connected to the bottom of the housing 5 .

[0041] It can minimize the vibration of the device with the greatest efficiency and reduce the wear between the internal parts of the device.

[0042] Among them, the small gear 2 13 and the small gear 1 11 are only provided with partial teeth and are located on both sides of the large gear 10 .

[0043] The large gear 10 can be driven to rotate at different time periods by the small gear 2 13 and the small gear 1 11, so that the nozzle 9 performs a semicircular motion above the extruded polyethylene tube.

[0044] The cooling pipe 17 is located inside the extrusion groove 19 and extends to the end of the extrusion groove 19 .

[0045] It can maximize the rapid cooling of materials at various locations inside the device and improve the efficiency of the cooling zone.

[0046] The working principle and use process of this utility model:

[0047] When the staff uses the device, the extruded polyethylene tube needs to be cooled. First, by starting the motor 2 14 and the motor 1 12, and then starting the nozzle 9, the motor 2 14 and the motor 1 12 drive the pinion 2 13 and the pinion 1 11 to rotate in opposite directions. When the pinion 2 13 is meshed with the large gear 10, the large gear 10 will be driven to rotate. When the pinion 11 and the large gear 10 are meshed with each other, the large gear 10 will be driven to rotate. As the pinion 11 and the pinion 2 13 drive the large gear 10 to rotate at different time periods respectively, the nozzle 9 makes a semi-circular motion above the extrusion groove 19, and the liquid inside the cooling box 6 enters the interior of the nozzle 9 through the water pipe 7 and is sprayed out.

[0048] When the device is started, due to its large weight, the entire device will vibrate. When the device vibrates, it will drive the shell 5 to move downward and upward. When the shell 5 moves downward, it will drive the top of the damper 4 to move downward. When the top of the damper 4 moves downward, the top of the spring 3 will shrink downward. When the damper 4 and the top of the spring 3 are compressed downward, the shell 5 will move as the top of the spring 3 and the damper 4 move downward. When the spring 3 and the damper 4 are compressed to the extreme, the spring 3 and the damper 4 will drive the shell 5 to move upward.
