Description

Technical Field

[0001] The present application relates to the field of plastic processing, and in particular to a plastic processing mixer. Background Art

[0002] Plastic mixer is a kind of equipment that uses the principle of rapid rotation to achieve the purpose of uniform mixing. In the plastic industry, it is mainly used for mixing plastic particles, and is often used for large-capacity plastic dyeing and granulation, modification, recycled material recycling, and mixing between plastic particles such as PVC, TPR, TPE, PP, and PE. It not only replaces traditional manual mixing and greatly improves production efficiency, but also mixes evenly, effectively improving product quality.

[0003] Announcement No. CN 220638517 U discloses a mixer for plastic processing, in which a stirring component is gradually raised by a lifting component. When the stirring component rises to a specified position, plastic particles to be stirred are put into a stirring barrel. A staff member adjusts the stirring component according to the height of the plastic particles to be stirred in the stirring barrel. After the stirring component is adjusted, the stirring component is gradually lowered by the lifting component. When the stirring component is lowered to a specified position, the stirring component is started, and the stirring barrel is fixed by a limiting component. At this time, the stirring component will be placed in the stirring barrel, and the plastic particles in the stirring barrel can completely cover the stirring equipment on the stirring component, thereby preventing the stirring equipment not covered by the plastic from being unable to stir the plastic particles during the stirring process.

[0004] However, there are some defects in the above scheme: although the above scheme is provided with a stirring structure with adjustable height, so that the plastic particles inside the stirring barrel can completely cover the stirring device on the stirring component, the stirring component is fixed in position during the stirring process, and the stirring of the plastic is at a horizontal height, resulting in a long stirring time and reduced stirring efficiency. In addition, the size of the stirring rod is fixed, and it is difficult to adapt to the use of a stirring barrel with an inner diameter size, and the entire rod needs to be replaced, which reduces its practicality.

[0038] Among them, the elastic member 260 includes a spring 261 and a pressure rod 262, the rotating shaft 240 is provided with a connecting groove 241, the spring 261 is arranged in the connecting groove 241, the pressure rod 262 slides through the connecting groove 241, and the pressure rod 262 is fixedly connected to the sleeve 250, the pressure rod 262 is close to the arc wedge block 270, by arranging the spring 261 and the pressure rod 262, after the pressure rod 262 squeezes the spring 261, the elastic recovery effect of the spring 261 is used to push the pressure rod 262 to drive the sleeve 250 to reset.

[0039] Specifically, the rotating shaft 240 is provided with a limiting plane 242 , and the inner wall of the sleeve 250 is in contact with the limiting plane 242 . The limiting plane 242 is used to limit the relative rotation of the rotating shaft 240 and the sleeve 250 , and the guide sleeve 250 can only move axially along the rotating shaft 240 .

[0040] In this embodiment, the telescopic stirring rod 280 includes a fixed tube 281, a sliding rod 282, a threaded rod 283 and a positioning nut 284. The fixed tube 281 is fixedly connected to the sleeve 250, and one end of the sleeve 250 is slidably set in the fixed tube 281. The threaded rod 283 is fixedly connected to the sliding rod 282 and slides through the fixed tube 281. The positioning nut 284 is threadedly sleeved on the threaded rod 283. By setting the fixed tube 281, the sliding rod 282, the threaded rod 283 and the positioning nut 284, the sliding rod 282 drives the threaded rod 283 to slide and adjust the length in the sliding rod 282, thereby adjusting the overall length, and then tightening and fixing it with the positioning nut 284 to achieve the purpose of adjusting the length of the stirring rod.

[0042] The working principle of the plastic processing mixer is as follows: during use, the mixing barrel 120 filled with plastic raw materials is placed on the bottom plate 110, and the slider 121 is placed in the slide groove 111 for pushing. The slider 121 moves to the bottom of the slide groove 111 and moves into place, and then the slide groove 111 is started, and then the hydraulic cylinder 210 is started to drive the stirring mechanism to move down into the mixing barrel 120, and the telescopic stirring rod 280 enters the barrel and is covered with plastic, and then the motor 230 is started to drive the rotating shaft 240 to rotate, and the rotating shaft 240 drives the sleeve 250 to rotate, and the sleeve 250 drives the telescopic stirring rod 280 to rotate to stir the plastic raw materials. During the rotation, the pressure rod 262 contacts the arc wedge block 270, and is guided by the inclined surface limit of the arc wedge block 270. The pressure rod 262 drives the sleeve 250 to move downward, and the pressure rod 262 squeezes the spring 261. At the same time, the sleeve 250 drives the telescopic stirring rod 280 to move downward. When the pressure rod 262 passes over the arc wedge block 270, the elastic recovery effect of the spring 261 pushes the pressure rod 262 to drive the sleeve 250 to reset and move upward. Such a cycle enables the telescopic stirring rod 280 to switch stirring at different horizontal planes, effectively improving the stirring efficiency. Furthermore, for stirring barrels 120 with different inner diameters, the positioning nut 284 can be loosened first, and the sliding rod 282 drives the threaded rod 283 to slide and adjust the length in the sliding rod 282, thereby adjusting the overall length, and then the positioning nut 284 is tightened and fixed to achieve the purpose of adjusting the length of the stirring rod, which greatly improves practicality.

[0043] It should be noted that the specific models and specifications of the electric telescopic rod 131, the hydraulic cylinder 210 and the motor 230 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0044] The power supply and principle of the electric telescopic rod 131, the hydraulic cylinder 210 and the motor 230 are clear to those skilled in the art and will not be described in detail here.

[0045] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application.
