After the production of PE pipe is completed, it is necessary to remove impurities from the inner wall. The "pipe inner wall impurity removal device for wear-resistant PE pipe production" disclosed in the application number "CN215997926U" has solved the technical problem of inconvenience in cleaning the inner wall of PE pipes of different diameters. Although there are technical disadvantages, there are still many defects in the actual use of similar structure devices. For example, the overall structure is relatively simple, and only the impurities and foreign matter that fall off the inside can be removed by a brush, but the burrs adhered to the inner wall of the PE pipe cannot be removed, resulting in limited quality of impurity removal on the inner wall of the PE pipe; at the same time, it is not possible to recycle the impurities after removal, and most of the time, the staff need to manually collect the cleaned impurities, which increases the workload of the staff. For this reason, we designed a pipe inner wall impurity removal device for PE pipe production to solve the above problems. Utility Model Content

[0023] The following will be combined with the drawings in 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 in 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.

[0024] See also Figure 1-7 The utility model provides a technical solution: a pipe inner wall impurity removal device for PE pipe production, comprising a support mechanism 1 and an impurity removal mechanism 2 mounted above the support mechanism 1, and a recovery mechanism 3 installed on the front of the support mechanism 1, the support mechanism 1 comprises a base 101, a limiting groove 103 is arranged at the central position of the top of the base 101, both sides of the top of the base 101 are fixedly installed with a limiting push rod 106 through a support plate 105, and a clamping plate 107 is fixedly installed at the output end of the limiting push rod 106;

[0025] The impurity removal mechanism 2 includes an electric push rod 201, a fixed plate 202 is fixedly installed at the output end of the electric push rod 201, and an impurity removal motor 203 is fixedly installed at the lower back of the fixed plate 202, and an axle 209 is fixedly installed at the output end of the impurity removal motor 203 through the fixed plate 202, and a rotating rod 4 is fixedly installed on the front of the axle 209, and an impurity removal reel 401 is fixedly installed on the outside of the rotating rod 4, a sleeve 204 is fixedly installed below the front of the fixed plate 202, and the sleeve 204 is sleeved on the outside of the axle 209, and an air blowing pipe 205 is fixedly installed on the top of the sleeve 204;

[0026] The recovery mechanism 3 includes a mounting sleeve 301 and a closed ring 303 . A mounting shaft 302 is rotatably mounted on the top of the mounting sleeve 301 , a collecting bag 305 is fixedly mounted on the front of the closed ring 303 , and a sealing ring 304 is fixedly mounted on the back of the closed ring 303 .

[0027] Based on the above-mentioned structure, the inner wall impurity removal device for the PE pipe production is composed of a support mechanism 1, an impurity removal mechanism 2 and a recovery mechanism 3, wherein the support mechanism 1 supports and fixes the device during operation, the impurity removal mechanism 2 removes impurities from the inner wall of the PE pipe, and the recovery mechanism 3 recovers the impurities cleaned by the device, which is convenient for the staff to centrally process in the later stage. Specifically, during the working process, the base 101 can support the PE pipe, and the limit groove 103 can be placed on the base 101 when the PE pipe is placed on the base 101. The limit push rod 106 extends to push the clamping plate 107, so that the outer wall of the PE pipe in the limit groove 103 can be clamped and limited by the clamping plate 107, ensuring the stability of the device when removing impurities from the inner wall of the PE pipe. The electric push rod 201 can push the fixed plate 202 forward by contraction. When the fixed plate 202 moves forward, the impurity removal motor 203 drives the rotating rod 4 and the impurity removal reel 401 to rotate through the shaft 209, and the impurity removal reel 401 enters the inner part of the PE pipe fixed by the limit in the rotating state. The burrs and residues on the inner wall can be removed, and the function of removing the burrs and residues on the inner wall of the PE pipe is realized, which greatly improves the quality of the device for removing impurities on the inner wall of the PE pipe, and increases the cleanliness of the inner wall of the PE pipe after impurities are removed. The air blowing pipe 205 installed on the top of the sleeve 204 can clean the burrs and residues removed by the impurity removal reel 401 by blowing. The closed ring 303 can be fitted with the front side of the PE pipe fixed by limiting, and the installation sleeve 301 and the installation shaft 302 can movably install the closed ring 303, so that the closed ring 303 can be contacted and fitted with the front side of the PE pipe by rotation. The sealing ring 304 increases the sealing performance of the closed ring 303 when it is fitted with the front side of the PE pipe, so that the burrs and residues cleaned by the air blowing pipe 205 can be automatically recovered through the closed ring 303 and the collection bag 305, which is convenient for the staff to carry out centralized processing later, avoiding the situation that the staff need to manually remove the burrs and residues removed from the PE pipe later, and reducing the workload of the staff.

[0028] Furthermore, two groups of air jet heads 206 are fixedly installed on the front of the air blowing pipe 205, and a connecting air pipe 207 is fixedly installed on the back of the air blowing pipe 205. The air jet heads 206 can eject the high-pressure gas inside the air blowing pipe 205 through two air streams, so that the burrs and residues after removal can be discharged, and the connecting air pipe 207 facilitates the connection of the air blowing pipe 205 with an external high-pressure gas device, so that the inside of the PE pipe can be cleaned by high-pressure gas.

[0029] Further, two sets of fixing frames 208 are fixedly installed on both sides of the electric push rod 201, and the bottom of the fixing frame 208 is fixedly connected to the top of the base 101. Among them, the fixing frame 208 can support and fix the electric push rod 201, thereby increasing the stability of the electric push rod 201 during operation.

[0030] Furthermore, a return spring 306 is sleeved on the bottom of the installation shaft 302, and an arm 307 is fixedly installed on one side of the installation shaft 302. The arm 307 can connect the closed ring 303 and the installation shaft 302, and the return spring 306 can provide elastic force to the closed ring 303, so that the closed ring 303 fits with the front of the PE pipe in an elastic manner.

[0031] Furthermore, a limiting plate 104 is fixedly installed on the back of the limiting groove 103, and a concave groove 108 is provided on the inner wall of the clamping plate 107. The limiting plate 104 can limit the back of the PE pipe when it is placed in the limiting groove 103, and the concave groove 108 increases the contact area between the clamping plate 107 and the outer wall of the PE pipe, thereby improving the stability of the clamping plate 107 when clamping and fixing the PE pipe.

[0032] Furthermore, fixing holes 102 are provided on both sides of the base 101. The fixing holes 102 facilitate bolts to fix the base 101, thereby increasing the overall stability of the device when removing impurities from the inner wall of the PE pipe.
