[0028] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0029] Please see Figures 1-8 As shown, the purpose of this embodiment is to provide an automatic mixing machine for PE blending and modification, including a housing 1. Two parallel rotating shafts are rotatably arranged inside the housing 1. A feed pipe 11 is fixedly connected to one side of the top of the housing 1. The rotating shafts include a first rotating shaft 2 and a second rotating shaft 3, and the first rotating shaft 2 and the second rotating shaft 3 rotate in opposite directions. A slide plate 4 is slidably arranged inside the housing 1. The slide plate 4 is used to throw the material that has settled to the bottom upwards for mixing. A discharge port 12 is opened on one side of the bottom of the housing 1. A receiving box 13 is connected to the bottom of the discharge port 12.
[0030] The feed pipe 11 includes a connecting pipe 111 that communicates with the chassis 1. The connecting pipe 111 has a first feed port 112 and a second feed port 113 symmetrically connected on both sides. The first feed port 112 is used to inject PE material, and the second feed port 113 is used to inject additives.
[0031] The inner wall of the connecting pipe 111 has several guide plates 114 arranged in a spiral shape, and the guide plates 114 are inclined. Since the PE material and the additives enter the connecting pipe 111 from two inlets respectively, they will collide and intertwine under the action of the guide plates 114, thereby achieving preliminary mixing. This design helps to reduce the time and energy required for mixing in the casing 1, thereby improving the efficiency of the entire mixing process.
[0032] Both ends of the first rotating shaft 2 and the second rotating shaft 3 are fixedly provided with helical blades 21. The main function of the helical blades 21 is to push the material to move along the direction of the rotating shaft. Several stirring blades 22 are fixedly provided on the rotating shaft. The stirring blades 22 are located between the helical blades 21. The main function of the stirring blades 22 is to further mix and disperse the material. When the rotating shaft rotates, the stirring blades 22 will cut, stir and fold the material, thereby achieving more thorough mixing. Moreover, the stirring blades 22 on the first rotating shaft 2 and the second rotating shaft 3 are staggered, which can enhance the interaction between the materials, improve the mixing efficiency, and also avoid the stirring blades 22 colliding with each other.
[0033] The first rotating shaft 2 is fixedly connected to one end of the first motor 14, and the second rotating shaft 3 is fixedly connected to one end of the second motor 15. The motors are fixedly connected to the outer wall of the housing 1. The motors drive the two rotating shafts to rotate in opposite directions to ensure that the material is evenly distributed in the housing 1 and avoid the problem of material agglomeration or uneven mixing.
[0034] The material enters through the feed pipe 11 and mixes between the spiral blades 21 at one end of the first rotating shaft 2 and the second rotating shaft 3. As the material moves, it is conveyed to the area of the stirring blades 22 in the middle for further mixing, and then moves to the spiral blades 21 at the other end for final mixing. Subsequently, it enters the receiving box 13 through the discharge port 12. To ensure the uniformity of the material mixing, the receiving box 13 is connected to a conduit 131 on its side wall. One end of the conduit 131 is located above the second feed port 113. Unmixed material can be pumped back to the feed pipe 11 through the conduit 131 for remixing.
[0035] Because the materials may sink to the bottom during the mixing process, resulting in uneven mixing, a slide plate 4 is set up to throw the sinking materials upwards so that they can enter the space between the rotating shafts for mixing. The slide plate 4 is an inclined arc shape, which not only facilitates the gradual movement of materials towards the discharge port 12 under the action of gravity, but also forms a natural material flow channel on the slide plate 4. Connecting plates 41 are fixedly connected to both sides of the slide plate 4, and several fixing strips 42 are fixedly set on the slide plate 4. The fixing strips 42 are evenly distributed along the length of the slide plate 4. The main function of the fixing strips 42 is to slow down the speed at which the materials sinking on the slide plate 4 are guided to the discharge port 12, so that the materials stay on the slide plate 4 for a longer time, thereby increasing the contact opportunity with the stirring blades on the rotating shaft and improving the mixing uniformity. A baffle 43 is fixedly connected to one end of the slide plate 4. The side wall of the baffle 43 is in contact with the inner wall of the receiving box 13. The baffle 43 acts as a seal to prevent the mixed materials from entering the gap between the bottom of the slide plate 4 and the inner wall of the casing 1.
[0036] The side wall of the casing 1 is provided with a slide groove 16. The connecting plate 41 is slidably installed in the slide groove 16. A cylinder 5 is fixedly installed at the center of the bottom of the casing 1. The output shaft of the cylinder 5 is fixedly connected to the bottom of the slide plate 4. When the cylinder 5 works, its output shaft will drive the slide plate 4 to reciprocate along the slide groove 16, thereby throwing the material at the bottom upwards and realizing the re-mixing of the material.
[0037] In practical use, the first motor 14 and the second motor 15 are started, causing the first rotating shaft 2 and the second rotating shaft 3 to rotate in opposite directions. PE material and additives are added to the feed pipe 11 through the first feed port 112 and the second feed port 113. Within the connecting pipe 111, the material undergoes initial collision and mixing due to the action of the guide plate 114. The material enters the casing 1 through the feed pipe 11 and is first pushed and initially mixed by the spiral blades 21 at one end of the first rotating shaft 2 and the second rotating shaft 3. As the material moves, they... The material is conveyed to the middle mixing blade 22 area, where it is further mixed. The material continues to move between the spiral blades 21 at the other end for final mixing. During this process, the cylinder 5 drives the slide plate 4 to reciprocate along the chute 16, throwing the material at the bottom upwards so that it can re-enter the mixing area between the rotating shafts. The uniformly mixed material enters the receiving box 13 through the discharge port 12. If necessary, the incompletely mixed material can be pumped back to the feed pipe 11 through the conduit 131 for remixing. After mixing is completed, the power is turned off.
[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
