Description

Technical Field

[0001] This utility model relates to the field of polyethylene pipe production, and in particular to a mixing device for polyethylene pipe production. Background Technology

[0002] Polyethylene pipes are plastic pipes made primarily of polyethylene resin through processes such as extrusion molding. They are characterized by their light weight, corrosion resistance, and good flexibility. Uniform mixing of polyethylene resin with various additives is essential to ensure stable pipe performance and improve the pipe's quality, toughness, and other properties.

[0003] In the process of realizing this application, the inventors discovered the following problems with the prior art: the existing mixing devices used for the production of polyethylene pipes generally include structures such as a stirring rod, a shell, an inlet, and an outlet. The existing stirring rods are all horizontal or vertical stirring, which is not thorough enough and the mixing efficiency is not high enough. At the same time, most of the existing stirring rods are fixed together with the cover or shell, and can only be cleaned by spray gun or manual cleaning when cleaning is required. They cannot be disassembled for more professional cleaning.

[0004] Therefore, those skilled in the art have provided a mixing apparatus for the production of polyethylene pipes to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a mixing device for polyethylene pipe production. The mixing mechanism enables the raw materials to be mixed more fully and faster, and the snap-fit ​​mechanism allows the mixing rod to be cleaned more thoroughly.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mixing device for producing polyethylene pipes, comprising a stirring mechanism, a clamping plate, and a clamping mechanism. The stirring mechanism includes a housing, a gear, a first stirring rod, and a dual-head motor. A toothed ring is fixedly connected to the middle of the outer wall of the housing, and the toothed ring meshes with the gear. A second stirring rod is fixedly connected to the output end of the dual-head motor.

[0007] The locking mechanism includes a locking block. The bottom inner wall of the locking block is slidably connected to the top outer wall of the first stirring rod. A first screw is threadedly connected to the inner wall of the locking block. A second screw is slidably connected to the inner wall of the front end of the first screw away from the locking block. The first screw passes through the top inner wall of the first stirring rod and is slidably connected to the top inner wall of the first stirring rod.

[0008] Furthermore, a protruding ring is fixedly connected to the upper part of the outer wall of the housing, and the outer wall of the protruding ring is slidably disposed on the inner wall of the card plate, and the inner wall of the card plate and the outer wall of the housing are slidably connected.

[0009] Furthermore, a No. 1 motor is fixedly installed on one side of the bottom of the card plate, and the output end of the No. 1 motor is fixedly connected to the center of the top of the gear.

[0010] Furthermore, a box is fixedly installed at the bottom of the first stirring rod, and the inner wall of the box is fixedly connected to the dual-head motor.

[0011] Furthermore, the top of the housing is connected to a cover by multiple bolts, and a second motor is fixedly connected to the inner wall of the cover. The output end of the second motor is fixedly connected to the center of the top of the card block.

[0012] Furthermore, two No. 1 plates are fixedly connected to one side of the outer wall of the card block, and the inner walls of the two No. 1 plates are threadedly connected to the outer wall of the No. 2 screw.

[0013] Furthermore, the card plate is fixedly provided with support legs near the four corners at the bottom.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model proposes a mixing device for polyethylene pipe production. When the No. 2 motor starts working, the No. 1 stirring rod rotates clockwise. The No. 1 stirring rod drives the box body, the double-headed motor, and the two No. 2 stirring rods to rotate clockwise, mixing the raw materials in the shell. Then, the No. 1 motor starts working, driving the gear to rotate clockwise. The gear further drives the gear ring to rotate counterclockwise. The gear ring further drives the shell and the convex ring to rotate counterclockwise along the inner wall of the clamping plate. The two No. 2 stirring rods can fully mix the raw materials at the bottom of the shell, preventing them from settling to the bottom. Furthermore, by rotating the No. 1 stirring rod, the No. 2 stirring rod, and the shell in opposite directions, the raw materials inside the shell are mixed more thoroughly, resulting in faster mixing efficiency.

[0016] 2. The mixing device for polyethylene pipe production proposed in this utility model involves cleaning the No. 1 and No. 2 mixing rods. First, the cover is moved upwards along with the bottom No. 1 and No. 2 mixing rods and removed from the inside of the housing. Then, the No. 2 screw is rotated so that it slides out from the inner wall of the right end of the No. 1 screw. Next, the No. 1 screw is rotated so that it slides out from the top of the No. 1 mixing rod. Then, the No. 1 and No. 2 mixing rods can be removed for more professional cleaning, ensuring that there is no raw material residue on the outer wall of the No. 1 and No. 2 mixing rods during subsequent mixing.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-6 This utility model provides an embodiment of a mixing device for polyethylene pipe production, comprising a stirring mechanism 1, a clamping plate 2, and a clamping mechanism 3. The stirring mechanism 1 includes a housing 104, a gear 102, a first stirring rod 106, and a dual-head motor 109. A toothed ring 101 is fixedly connected to the middle of the outer wall of the housing 104, and the toothed ring 101 meshes with the gear 102. A second stirring rod 107 is fixedly connected to the output end of the dual-head motor 109. The clamping mechanism 3 includes a clamping block 301, the bottom inner wall of the clamping block 301 is slidably connected to the top outer wall of the first stirring rod 106, a first screw 302 is threadedly connected to the inner wall of the clamping block 301, and a second screw 303 is slidably connected to the inner wall of the front end of the first screw 302 away from the clamping block 301. The first screw 302 penetrates the top inner wall of the first stirring rod 106 and is slidably connected to the top inner wall of the first stirring rod 106.

[0027] Specifically, the raw materials enter through the feed inlet on one side of the lid. Motor 105 operates, driving the first stirring rod 106 to rotate clockwise, along with the housing 108, the dual-head motor 109, and the two second stirring rods 107, mixing the various raw materials inside the shell 104. Then, motor 103 operates, driving gear 102 to rotate clockwise. Gear 102 drives gear ring 101 to rotate counter-clockwise. Gear ring 101 drives the inner shell 104 and the convex ring 110 to rotate counter-clockwise along the inner wall of the clamping plate 2. Through the rotation of the first stirring rod 106 in both directions, and in conjunction with the two second stirring rods 107, the raw materials inside the shell 104 are mixed more thoroughly, resulting in higher mixing efficiency. It is necessary to clean the first stirring rod 106 and the second stirring rods 107. When moving rod 107, first remove the multiple bolts threaded to the top of the housing 104. Then, move the cover and the bottom stirring rods 106 and 107 upwards out of the housing 104. Rotate the second screw 303, and the second screw 303 will move forward along the two threaded plates 304 and slide out from inside the first screw 302. Then rotate the first screw 302 to make it slide out from the top of the first stirring rod 106. The first stirring rod 106 and the second stirring rod 107 can then be removed for professional cleaning. When resetting, reset the top of the first stirring rod 106. After the first screw 302 passes through the inner wall of the first stirring rod 106, after several adjustments, make the through hole at the right end of the first screw 302 correspond to the threaded holes on the inner wall of the two plates 304.

[0028] Reference Figures 1-6 A protruding ring 110 is fixedly connected to the upper part of the outer wall of the shell 104. The outer wall of the protruding ring 110 is slidably set on the inner wall of the card plate 2. The inner wall of the card plate 2 is slidably connected to the outer wall of the shell 104. A first motor 103 is fixedly installed on one side of the bottom of the card plate 2. The output end of the first motor 103 is fixedly connected to the center of the top of the gear 102. A box 108 is fixedly installed at the bottom of the first stirring rod 106. The inner wall of the box 108 is fixedly connected to the double-headed motor 109. A cover is connected to the top of the shell 104 by multiple bolts. A second motor 105 is fixedly connected to the inner wall of the cover. The output end of the second motor 105 is fixedly connected to the center of the top of the card block 301. Two first plates 304 are fixedly connected to one side of the outer wall of the card block 301. The inner walls of the two first plates 304 are threadedly connected to the outer wall of the second screw 303. Support legs are fixedly installed at the bottom of the card plate 2 near the four corners.

[0029] Specifically, the convex ring 110 is secured to the inner wall of the clamping plate 2, providing support for the whole structure. The clamping plate 2 provides fixation for the first motor 103, which provides power for the rotation of the gear 102. The cover is movably embedded in the inner wall of the top of the housing 104 and is fixed to the top of the housing 104 by multiple bolts. To prevent the cover from flying off when the housing 104 rotates, multiple support legs provide support for the overall structure. The box 108 prevents the dual-head motor 109 from being corroded by water, which could cause a short circuit and loss of performance.

[0030] Working principle: Raw materials are fed into the inlet on one side of the cover at the top of the shell 104. Then, the second motor 105 is started to drive the first stirring rod 106 to rotate clockwise. The first stirring rod 106 drives the bottom box 108, the double-headed motor 109, and the two second stirring rods 107 to rotate clockwise to mix the raw materials inside the shell 104. At this time, the first motor 103 is started. The output end of the first motor 103 rotates to drive the gear 102 to rotate clockwise. The gear 102 drives the gear ring 101 to rotate counterclockwise. The gear ring 101 drives the inner wall of the shell 104 and the convex ring 110 to rotate counterclockwise along the inner wall of the clamping plate 2, which is opposite to the rotation direction of the first stirring rod 106 inside the shell 104, so that the raw materials are more fully mixed. The mixed raw materials can be discharged from the electric valve at the bottom rear end of the shell 104.

[0031] Secondly, after the mixing is finished, when it is necessary to clean the No. 1 mixing rod 106 and the bottom No. 2 mixing rod 107, the multiple bolts threaded on the top of the housing 104 can be removed. Then, the cover is moved up, which will move the bottom No. 1 mixing rod 106 and the bottom No. 2 mixing rod 107 up. Then, the No. 2 screw 303 is rotated so that it slides out from the right end of the No. 1 screw 302. Then, the No. 1 screw 302 is rotated so that it slides out from the top of the No. 1 mixing rod 106. The No. 1 mixing rod 106 and the bottom No. 2 mixing rod 107 can then be removed for more professional cleaning.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
