Description

Technical Field

[0001] The invention belongs to the technical field of polyethylene pipe production, and particularly relates to a self-dosing device and a dosing method for polyethylene pipe production. Background Art

[0002] Polyethylene pipe is a plastic pipe with the characteristics of corrosion resistance, impact resistance and long service life. It is mainly used for water supply pipes and gas pipes.

[0003] The existing technology has the following problems: 1. The existing self-provisioning device for polyethylene pipe production uses a gravity sensor to weigh the raw materials and auxiliary materials dropped into the weighing box. However, when the existing device continuously adds materials, the impact of the falling materials will cause the weighing box to vibrate instantaneously, causing the reading of the gravity sensor to fluctuate, resulting in false weight or weight loss, and causing ratio errors. 2. The existing self-mixing device for polyethylene pipe production does not have a stirring and anti-blocking function in the material barrel. When feeding, the raw materials or auxiliary materials are easily blocked in the material barrel. At the same time, when the device is not in use, the upper end of the material barrel cannot be sealed, and impurities are easy to fall into the material barrel and contaminate the raw materials or auxiliary materials. 3.

[0012] Furthermore, the side edges of the transverse scraper and the longitudinal scraper are tangent to the inner wall of the mixing box, and the oblique rods and the longitudinal scraper, as well as the oblique rods and the transverse scraper are fixed by welding.

[0013] Furthermore, a batching method for a self-batch device for producing polyethylene pipes comprises the following steps: Step 1: When batching, add the raw materials and auxiliary materials into two material buckets respectively. When the solenoid valve 1 is opened, the material enters the discharge box. When the motor 2 is turned on, the rotating rod 1 and the roller are driven to rotate. The material falls into the groove on the side of the roller. After the roller rotates and drives the groove to correspond to the position of the discharge pipe, the material falls into the weighing box through the discharge pipe. The weighing box weighs the material through the gravity sensor. After reaching the appropriate weight, the solenoid valve 1 and the motor 2 are closed. When the solenoid valve 2 is opened, the material falls into the feed port and enters the mixing box. By opening a number of grooves at equal distances on the side of the roller, the weighing box can be fed intermittently. After changing to intermittent discharge, the weighing box can be kept still before each discharge. The gravity sensor can accurately collect stable weight data to ensure the ratio accuracy of the raw materials and auxiliary materials. Turning on the electric push rod can push the slide to move in the groove, thereby adjusting the amount of material received in the groove and improving the practicality of the equipment. Step 2: After the raw materials or auxiliary materials are added into the material bucket, the motor 3 is turned on to drive the rotating rod 3 and the worm to rotate. The worm drives the rotating rod 2 to rotate in the fixed frame through the worm gear. The rotation of the rotating rod 2 drives the spiral blade to rotate in the material bucket to transport the material in the material bucket to prevent the material from being blocked in the material bucket. When the device is not in use, the fixing bolt is unscrewed from the fixing hole. Then the sealing cover can be pushed to slide on the rotating rod 2 until the sealing cover is sleeved on the upper end of the material bucket to achieve the effect of sealing the upper end of the material bucket. A sealing gasket is arranged on the inner wall of the sealing cover to improve the sealing between the sealing cover and the material bucket. The sealing cover can be set to seal the upper end of the material bucket to prevent external impurities from falling into the material bucket and causing contamination of the material. Step 3: After the appropriate amount of raw materials and auxiliary materials fall into the mixing box, turn on the motor to drive the rotating shaft and the stirring rod to rotate to mix and stir the materials. The mixed materials are discharged through the discharge port. When the rotating shaft rotates, the horizontal scraper is driven to rotate through the connecting rod, and the rotation of the horizontal scraper drives the vertical scraper to rotate. The rotation of the vertical scraper and the horizontal scraper can clean the inner wall of the mixing box to prevent the material from adhering to the inner wall of the mixing box and being difficult to clean. A diagonal rod is set between the longitudinal scraper and the horizontal scraper to make the longitudinal scraper and the horizontal scraper more firm.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention sets a material unloading component and weighs the material through a gravity sensor. When the appropriate weight is reached, the solenoid valve 1 and the motor 2 are closed, and the solenoid valve 2 is opened to allow the material to fall into the feed port and enter the mixing box. By providing a number of grooves equidistantly on the side of the roller, intermittent feeding can be performed on the weighing box. After changing to intermittent unloading, the weighing box can be left stationary before each unloading. The gravity sensor can accurately collect stable weight data to ensure the ratio accuracy of raw materials and auxiliary materials. Turning on the electric push rod can push the slide to move in the groove, thereby adjusting the amount of material received in the groove and improving the practicality of the equipment.

[0015] 2. The present invention sets an anti-blocking component. After the raw materials or auxiliary materials are added into the material barrel, the motor three is turned on to drive the rotating rod three and the worm to rotate. The worm drives the rotating rod two to rotate in the fixed frame through the worm gear. The rotation of the rotating rod two drives the spiral blade to rotate in the material barrel to transport the material in the material barrel, thereby preventing the material from being blocked in the material barrel. A sealing cover is set to seal the upper end of the material barrel to prevent external impurities from falling into the material barrel and causing contamination of the material.

[0016] 3. The present invention sets a scraper assembly. After an appropriate amount of raw materials and auxiliary materials fall into the mixing box, the motor is turned on to drive the rotating shaft and the stirring rod to rotate to mix and stir the materials. The mixed materials are discharged through the discharge port. When the rotating shaft rotates, the horizontal scraper is driven to rotate through the connecting rod, and the rotation of the horizontal scraper drives the longitudinal scraper to rotate. The rotation of the longitudinal scraper and the transverse scraper can clean the inner wall of the mixing box to prevent the material from adhering to the inner wall of the mixing box and being difficult to clean. A diagonal rod is set between the longitudinal scraper and the transverse scraper to make the longitudinal scraper and the transverse scraper more firm. BRIEF DESCRIPTION OF THE DRAWINGS
