[0002] After searching, the patent with publication number CN213648594U discloses an automatic feeding device for pipe processing. The device drives the transmission shaft to rotate through a driving motor, so that the transmission shaft drives the crushing blade to rotate, which is convenient for cutting and crushing PE raw materials, which is beneficial to improve the fineness of PE raw materials, thereby improving the subsequent hot melt efficiency. At the same time, it also avoids the large volume of PE raw materials clogging the inside of the hot melt extruder body, which is beneficial to improving the processing efficiency and service life of the hot melt extruder body.

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] PE pipe is one of the common pipes in water supply and drainage projects. It uses polyethylene as raw material. Polyethylene is widely used due to its high strength, high temperature resistance, corrosion resistance, non-toxicity and wear resistance. In the manufacturing process of PE pipe, hot melt extrusion technology is usually used. The PE raw material is heated and extruded by a hot melt extruder to form a continuous structure of the pipe. This production method ensures the stability and durability of PE pipes in use and is suitable for the needs of various water supply and drainage systems.

[0024] The rotation of the pulverizing blade in the existing device can play a certain role in cutting and crushing the PE raw materials. However, the fixed rotation range of the pulverizing blade will lead to low efficiency in cutting and crushing the PE raw materials in the crushing barrel. The main reason is that the fixed rotation range of the pulverizing blade limits the ability to flexibly respond to the characteristics of the PE raw materials and cutting requirements, thus affecting the uniformity of cutting and the quality of crushing. Figure 1-Figure 4 The embodiment provides an automatic feeding mechanism for pipe processing, including a crushing barrel 1, a top of the crushing barrel 1 is fixedly connected to a feeding pipe 11, and a peripheral surface of the crushing barrel 1 is fixedly connected to a material guide pipe 12.

[0025] refer to Figure 2-Figure 4As shown, the fixed rotation range of the crushing blade 25 will lead to low efficiency in cutting and crushing the PE raw material in the crushing barrel 1. The main reason is that the fixed rotation range of the crushing blade 25 limits the ability to flexibly respond to the characteristics of the PE raw material and cutting requirements, thereby affecting the uniformity of cutting and the quality of crushing. In order to ensure an efficient crushing process, the following settings are made: a crushing mechanism 2 for cutting and crushing PE raw materials is provided on the top of the crushing barrel 1, and the crushing mechanism 2 includes a motor 21 fixed on the top of the crushing barrel 1, and the motor 21 is a forward and reverse motor. The output end of the motor 21 is fixedly connected to a rotating shaft 22, and the inner wall of the crushing barrel 1 is fixedly connected to a threaded barrel 23. The rotating shaft 22 is sleeved inside the threaded barrel 23, and the outer wall of the rotating shaft 22 is rotatably connected to the inner wall of the threaded barrel 23. The bottom end of the rotating shaft 22 passes through the inner cavity of the threaded barrel 23 and extends to the outside of the threaded barrel 23. The bottom end of the rotating shaft 22 is fixedly connected to a mounting plate 24. Two telescopic components 26 are symmetrically arranged on the top of the mounting plate 24. The telescopic component 26 includes a telescopic rod 262 fixed to the top of the mounting plate 24. A telescopic barrel 261 is arranged on the top of the telescopic rod 262. The top of the telescopic barrel 261 is fixed on At the bottom of the crushing blade 25, the outer wall of the top of the telescopic rod 262 is fixedly connected with a slider, and the inner wall of the telescopic cylinder 261 is vertically provided with a slide groove, and the slider slides up and down along the height direction of the slide groove. The tops of the two telescopic components 26 are fixedly connected with the crushing blade 25, and the crushing blade 25 is threadedly connected to the outer wall of the threaded cylinder 23. When the crushing blade 25 is threadedly rotated and moved downward, the telescopic rod 262 gradually extends into the telescopic cylinder 261 through the downward movement of the telescopic cylinder 261. When the crushing blade 25 is threadedly rotated and moved upward, the telescopic rod 262 gradually protrudes out of the telescopic cylinder 261 through the upward movement of the telescopic cylinder 261. The motor 21 is started to drive the output end drive shaft 22 to rotate in the reverse direction in the threaded barrel 23, and the rotation of the shaft 22 drives the mounting plate 24 to rotate, and the rotation of the mounting plate 24 causes the telescopic assembly 26 to rotate synchronously, so that the crushing blade 25 rotates and moves downward on the outer wall of the threaded barrel 23 to cut and crush the PE raw material. During the process of the crushing blade 25 rotating and moving downward, the spacing between the crushing blades 25 will form a gradually narrowing process, which helps to produce finer and more uniform crushed particles; when the output end of the motor 21 drives the shaft 22 to rotate forward in the threaded barrel 23, the crushing blade 25 rotates and moves upward on the outer wall of the threaded barrel 23 to cut and crush the PE raw material. During the process of the crushing blade 25 rotating and moving upward, the spacing between the crushing blades 25 will form a gradually expanding process, and this change can adjust the uniformity of cutting and the quality of crushing as needed. By controlling the direction and speed of the motor 21, the spacing change between the crushing blades 25 can be flexibly adjusted to achieve a more accurate and efficient cutting effect. This process can be adjusted according to the characteristics and cutting requirements of the PE raw material to improve the uniformity of cutting and the quality of crushing.

[0026] refer to Figure 3-Figure 4As shown, the inner wall of the crushing barrel 1 is fixedly installed with an elastic screen 4 by a buckle, and the elastic screen 4 has an arc shape for screening the crushed PE raw materials. The bottom of the mounting plate 24 is fixedly connected with a conveying leaf 3 for rolling up the crushed PE raw materials that do not meet the standards for re-cutting and crushing. The conveying leaf 3 is located at the center of the top of the elastic screen 4, and the bottom end of the conveying leaf 3 is 1 cm away from the top of the elastic screen 4. The conveying leaf 3 is located at the center of the top of the elastic screen 4 and the bottom end is 1 cm away from the top of the elastic screen 4. It can effectively utilize gravity and power, improve the re-crushing efficiency, and reduce energy consumption, thereby optimizing the processing process of the PE raw materials. The cut and crushed PE raw material falls on the top of the elastic screen 4, which makes the elastic screen 4 elastic, so that the cut and crushed PE raw material bounces up to a height of ≤0.5 cm for screening. The PE raw material that meets the specifications enters under the elastic screen 4, and enters the loading barrel through the existing material guide plate and material guide pipe 12 for subsequent work; the non-compliant PE raw material is concentrated at the center of the elastic screen 4 along the inner cavity slope of the elastic screen 4, and is then continuously transported upward by the conveying blade 3. At this time, when the crushing blade 25 rotates and moves down to the bottom, the non-compliant PE raw material will be crushed again, ensuring that the out-of-specification PE raw material can be effectively processed and refined again.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
