Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, and particularly relates to a mixing device for an injection molding machine. Background Technique

[0002] An injection molding machine is the main molding equipment for forming various plastic products by using thermoplastic or thermosetting plastics with plastic molding dies, and can be mainly divided into three types: vertical, horizontal, and all-electric. The injection molding machine is also called an injection molding machine or injection; when feeding the injection molding machine, it is usually necessary to first use a mixing device to stir and mix various raw materials.

[0003] The existing mixing barrel is of an integrally formed structure and does not have a self-cleaning structure, resulting in difficulty for personnel to comprehensively clean the inside of the mixing barrel, with a relatively high cleaning difficulty, thus affecting the subsequent normal use of the mixing barrel. Therefore, we propose a mixing device for an injection molding machine. Content of the Utility Model

[0023] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0024] In the description of the present utility model, unless otherwise stated, "a plurality of" means two or more; the orientation or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0025] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] Such as Figure 1-7As shown in the figure, the utility model provides a technical solution: an injection molding machine mixing device, which includes a mixing barrel 1. A support frame 3 is fixedly installed at the top of the mixing barrel 1. A motor 2 is fixedly installed at the top of the support frame 3. A rotating shaft 4 is fixedly installed at the output end of the motor 2. The rotating shaft 4 penetrates through the support frame 3 and the top of the mixing barrel 1 respectively, and the rotating shaft 4 is rotationally connected to the mixing barrel 1 through a bearing. A stirring plate 5 is fixedly installed on the outer wall of the rotating shaft 4. A cleaning mechanism 6 is arranged near the top inside the mixing barrel 1;

[0027] The cleaning mechanism 6 includes an electric cylinder 601 and an annular scraping plate 602. The electric cylinder 601 is fixedly installed at the top of the mixing barrel 1. The piston rod of the electric cylinder 601 movably penetrates through the top of the mixing barrel 1. The annular scraping plate 602 is fixedly installed at the bottom end of the piston rod of the electric cylinder 601. The annular scraping plate 602 is slidably connected to the inner wall of the mixing barrel 1. A cavity 603 is formed inside the annular scraping plate 602. A spray head 604 is communicated with the bottom end of the annular scraping plate 602 and the cavity 603. A limiting through pipe 606 is communicated between the top end of the annular scraping plate 602 and the cavity 603. A limiting pipe hole 607 is formed at the top of the mixing barrel 1. The limiting through pipe 606 movably penetrates through the limiting pipe hole 607. A plate groove 605 is formed inside the annular scraping plate 602.

[0028] Specifically, in the above technical solution, after the injection molding machine mixing device is used up, the electric cylinder 601 can be started, and cleaning water is introduced through the limiting through pipe 606. The electric cylinder 601 drives the annular scraping plate 602 to move downward, so that the annular scraping plate 602 scrapes off the raw materials attached to the inner wall of the mixing barrel 1. The cleaning water enters the cavity 603 through the limiting through pipe 606, and finally sprays out onto the inner wall of the mixing barrel 1 through the spray head 604, thereby improving the cleaning quality of the inner wall of the mixing barrel 1. The scraped raw materials will fall to the bottom of the mixing barrel 1. Then, the operator can take out the plug 7 and open the cleaning port 8, so that the operator can take out the raw materials falling to the bottom of the mixing barrel 1 through the cleaning port 8, thereby completing the cleaning of the inside of the mixing barrel 1. Through the above structure, it is convenient for the operator to clean the inside of the mixing barrel 1 after use, reduces the cleaning difficulty, ensures the normal subsequent use of the mixing barrel 1, and solves the problem that the existing mixing barrel 1 is an integrally formed structure and does not have a self-cleaning structure, resulting in difficulty for the operator to comprehensively clean the inside of the mixing barrel 1, with a large cleaning difficulty, thus affecting the normal subsequent use of the mixing barrel 1.

[0029] Furthermore, the number of the electric cylinder 601, the limiting through pipe 606 and the limiting pipe hole 607 is two, and the limiting through pipe 606 is adapted to the limiting pipe hole 607;

[0030] Among them, by setting the limiting through pipe 606, the annular scraping plate 602 can be limited, and cleaning water can be introduced into the cavity 603 through the limiting through pipe 606.

[0031] Further, cleaning openings 8 are provided at the front and back of the mixing barrel 1 near the bottom end. A blocking block 7 is clamped in the cleaning opening 8, and the blocking block 7 is fixedly connected to the mixing barrel 1 by bolts;

[0032] Among them, by setting the blocking block 7, the cleaning opening 8 can be covered and sealed.

[0033] Further, the number of the spray nozzles 604 is several.

[0034] Further, a positioning pointer 12 is fixedly installed on the outer wall of the rotating shaft 4, and a positioning groove 13 is provided at the top end of the mixing barrel 1;

[0035] Among them, by setting the positioning pointer 12 and the positioning groove 13, when the cleaning mechanism 6 is in use, it can be ensured that the annular scraping plate 602 can move downward and the stirring plate 5 can pass through the plate groove 605 by observing that the positioning pointer 12 rotates to directly above the positioning groove 13, ensuring the normal use of the annular scraping plate 602.

[0036] Further, a feed pipe 11 is connected and provided at the top end of the mixing barrel 1, a discharge pipe 10 is connected and provided at one side of the mixing barrel 1 near the bottom end, a bottom plate 14 is fixedly installed at the bottom end of the mixing barrel 1, and a collection groove 9 is provided at the top end of the bottom plate 14. The collection groove 9 is arranged below the cleaning opening 8;
