Description

Technical Field

[0001] This utility model belongs to the field of PE material production technology, and in particular relates to a PE material production mixing device. Background Technology

[0002] Polyethylene (PE) is one of the most widely used thermoplastics, and is widely used in the manufacture of various products such as pipes, films, and packaging boards. In the production process of PE products, PE resin granules are usually thoroughly mixed with various additives such as color masterbatch and anti-aging agents for further processing.

[0003] Chinese patent CN214266564U discloses a mixing machine for PE pipe production. The paper describes a machine that includes a barrel and an electrical control box. The control box has two sets of switch buttons. A protective mechanism is located on the front of the control box, comprising a locking block and a protective cover. The locking block has a slot inside. A hinge is provided between one end of the protective cover and the control box. A baffle and a mounting block are located at the other end of the protective cover. A movable groove is provided inside the mounting block, and a movable strip is provided inside the movable groove. One end of the movable strip can pass through the slot. This invention, through its designed protective mechanism, facilitates the protection of the switch buttons. The protective cover protects the switch buttons, preventing accidental activation by operators and ensuring the mixing machine does not stop. This design also facilitates operation and improves the mixing efficiency and production progress of the mixing machine.

[0004] However, the above-mentioned scheme is not convenient for preventing material blockage during discharge. After the mixing is completed, due to the light weight of PE material, the powdery or granular material is prone to blockage at the discharge port, which will reduce the overall discharge rate. At the same time, the material at the bottom of the machine is not easy to turn over, requiring a longer mixing time and reducing the overall work efficiency. Therefore, it is necessary to design a PE material production mixing device. Utility Model Content

Figures 1 to 5 As shown: A PE material production mixing device includes a fixed frame 9; a controller 14 fixedly connected to one side of the inner top wall of the fixed frame 9; a housing 12 fixedly connected to the top of the fixed frame 9; a top cover 2 fixedly connected to the top of the housing 12 by bolts; a feed hopper 1 fixedly connected to the top of the top cover 2; a discharge pipe 11 fixedly connected to the bottom of the housing 12; a discharge pipe 10 fixedly connected to the lower end of one side of the discharge pipe 11; a servo motor 8 fixedly connected to the bottom of the discharge pipe 11; the output end of the servo motor 8 extends into the interior of the discharge pipe 11 and is fixedly connected to a rotating rod 15 by a coupling; a stirring rod 13 is provided at the top of the rotating rod 15; a spiral rod 6 is fixedly connected to the lower end of the surface of the stirring rod 13; and a main stirring blade 3 is fixedly connected to the upper end of the surface of the stirring rod 13; and an installation assembly 7 assembled between the stirring rod 13 and the rotating rod 15, which is used to assemble and disassemble the stirring rod 13.

[0020] It should be noted that some existing PE material production mixing devices still have certain shortcomings in actual use. After mixing, due to the light weight of PE material, powdery or granular materials are prone to clogging at the discharge port, which will reduce the overall discharge rate. At the same time, the material at the bottom of the machine is not easy to turn over, requiring a longer mixing time and reducing the overall work efficiency.

[0021] In a further preferred embodiment of the present invention, the main stirring blades 3 are distributed at equal angles and intervals on the surface of the stirring rod 13, and the main stirring blades 3 are arranged in a crisscross and inclined manner.

[0022] In this embodiment, the main stirring blades 3, which are arranged in a cross and inclined manner, are used to more thoroughly stir and mix the material inside the shell 12.

[0023] In a further preferred embodiment of the present invention, a secondary stirring blade 5 is fixedly connected at an equal angle to the lower end of the surface of the stirring rod 13, and one end of the secondary stirring blade 5 is welded to the surface of the stirring rod 13 in an integrated structure.

[0024] In this embodiment, the auxiliary stirring blade 5 is used to facilitate the stirring of the material at the lower end of the shell 12.

[0025] In a further preferred embodiment of the present invention, a scraper 4 is welded to one end of the auxiliary stirring blade 5, and the scraper 4 is in contact with the inner wall of the housing 12.

[0026] In this embodiment, the scraper 4 is used to prevent powdery materials from adhering to the inner wall of the housing 12. Example 2

[0027] Based on Example 1, a preferred embodiment of the PE material production mixing device provided by this utility model is as follows: Figures 1 to 5 As shown: The mounting component 7 includes: a slot 707 opened at the top of the rotating rod 15, and a bolt hole 706 opened in the inner bottom wall of the slot 707; a locking block 705 fixedly connected to the bottom end of the stirring rod 13; a vertical groove 701 opened inside the stirring rod 13; a vertical rod 703 movably connected inside the vertical groove 701, passing through the stirring rod 13 and the locking block 705; and a fixing bolt 702 fixedly connected to the bottom end of the vertical rod 703, which is threadedly engaged with the bolt hole 706.

[0028] In this embodiment, the disassembly and assembly of the stirring rod 13 and the rotating rod 15 are achieved by using the engagement between the locking block 705 and the slot 707, and by using the thread engagement between the fixing bolt 702 and the bolt hole 706.

[0029] In a further preferred embodiment of the present invention, a sealing plug 704 is engaged at the upper end of the vertical groove 701, and the area of ​​the top cross-section of the sealing plug 704 is greater than the area of ​​the opening cross-section of the vertical groove 701.

[0030] In this embodiment, the top of the vertical groove 701 can be sealed by the engaging sealing plug 704 to prevent material from entering the interior of the vertical groove 701.

[0031] In a further preferred embodiment of the present invention, the card block 705 and the card slot 707 form an engaging structure, and the card block 705 and the card slot 707 are cross-shaped.

[0032] In this embodiment, the reliability of the initial engagement and fixation between the stirring rod 13 and the rotating rod 15 is improved by utilizing the engagement between the cross-shaped locking block 705 and the slot 707.

[0033] In summary, firstly, different materials are added into the shell 12 through the feed hopper 1. Then, the servo motor 8 is started to drive the rotating rod 15 to rotate, which in turn causes the stirring rod 13 to rotate, causing the main stirring blade 3, the auxiliary stirring blade 5 and the spiral rod 6 to rotate, stirring and mixing the materials inside the shell 12. The rotation of the spiral rod 6 can also spirally transport the materials at the bottom of the shell 12 upwards, further improving the mixing effect. In addition, the rotation of the scraper 4 can prevent the powdery materials from adhering and remaining on the inner wall of the shell 12. After mixing, the servo motor 8 can be activated to make the screw rod 6 rotate in the opposite direction, so as to pressurize the material at the lower end of the shell 12 and convey it downward, so that it can be discharged more smoothly through the discharge pipe 10, avoiding material blockage and ensuring the material discharge rate. Simultaneously, after opening the top cover 2, the sealing plug 704 can be opened. The vertical rod 703 can be rotated with appropriate tools to rotate the fixing bolt 702 until it is completely disengaged from the bolt hole 706. Then, the stirring rod 13 can be pulled upwards to completely disengage the locking block 705 from the slot 707, making it easy to remove the main stirring blade 3, scraper 4, auxiliary stirring blade 5, and stirring rod 13 for thorough cleaning or maintenance. During installation, the locking block 705 is locked into the slot 707, and the vertical rod 703 is rotated in the opposite direction to tighten the fixing bolt 702 into the bolt hole 706, achieving a secure installation between the stirring rod 13 and the rotating rod 15. Then, the sealing plug 704 is locked into the vertical groove 701 to seal the top of the vertical groove 701 and prevent material from entering the interior of the vertical groove 701.
