Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to a mixer for plastic processing. Background Technology

[0002] Plastic is a material made of polymer compounds. Plastic raw materials are usually in granular form during processing. When processing plastic, a mixer is usually needed to mix, melt and homogenize the plastic raw materials.

[0003] An existing patent describes a mixer for plastic processing, with publication number CN215396176U. In its embodiment, a first motor and a second motor drive a limiting turntable and a stirring rod to rotate, so that the machine body can generate a centrifugal effect when rotating, thereby improving the mixing effect of plastic.

[0004] However, in actual use, the height of the mixing rod of the mixer is not adjustable and can only be mixed at a specified height. Since the size and density of plastic particles are different, if the raw materials in the specified height area are only mixed, the plastic particles will be unevenly distributed, resulting in low production efficiency. Utility Model Content

[0005] Given that the height of the existing stirring rod is not adjustable, which leads to low production efficiency, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a mixer for plastic processing, which aims to solve the problem that the height of the existing mixing rod is not adjustable, resulting in low production efficiency.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a mixer for plastic processing, comprising a mixing tank, a discharge pipe installed on one side of the mixing tank, and a valve installed on the top of the discharge pipe. A rotating shaft is rotatably connected inside the mixing tank. An array of agitator blades A is fixedly connected to the surface of the rotating shaft. An agitator blade B is movably connected inside the rotating shaft and above the agitator blades A. A lifting component is provided inside the rotating shaft. The lifting component includes a groove formed on the surface of the rotating shaft. A lifting block is movably sleeved inside the rotating shaft. One side of the agitator blade B extends through the groove into the interior of the rotating shaft and is fixedly connected to the lifting block. A lifting rod is fixedly connected to the top of the lifting block. The lifting rod extends to the top of the rotating shaft and is movably sleeved with it. The top of the rotating shaft extends to the top of the mixing tank. A driving component is installed on the top of the rotating shaft.

[0008] In a preferred embodiment of the plastic processing mixer of the present invention, the bottom of the lifting block is fixedly connected to a spring, the bottom of the spring is fixedly connected to the inner side of the rotating shaft, the bottom of the spring is fixedly connected to a fixing ring, and the bottom of the lifting block is provided with a cavity for connecting the spring. The spring provides a buffer force for the lifting block during the lifting process.

[0009] In a preferred embodiment of the plastic processing mixer of this utility model, the driving component includes a support rod fixed to the top of the mixing tank, an eccentric wheel movably connected to the inner side of the support rod, a motor installed on one side of the support rod, and the output end of the motor extending to the inner side of the support rod and fixedly connected to the eccentric wheel. The motor can drive the eccentric wheel to rotate and drive the hinge plate to raise and lower the lifting rod along the inside of the rotating shaft.

[0010] In a preferred embodiment of the plastic processing mixer of this utility model, a hinge plate is movably connected to the surface of the eccentric wheel, and the bottom of the hinge plate is movably connected to the lifting rod. The eccentric wheel and the lifting rod are connected through the hinge plate. The hinge plate allows the mixing paddle B to move up and down along the inside of the chute, thereby solving the problem that the existing method of mixing only the raw materials in a specified height area will result in uneven distribution of plastic particles.

[0011] In a preferred embodiment of the plastic processing mixer of this utility model, a U-shaped plate is fixedly connected to the surface of the rotating shaft, a scraper is fixedly connected to the outer side of the U-shaped plate, and an anti-settling plate is fixedly connected to the bottom of the U-shaped plate. One side of the scraper is in contact with the inner side of the mixing tank to scrape off the residue inside the mixing tank. The bottom of the anti-settling plate is in contact with the bottom of the mixing tank to prevent sedimentation at the bottom of the mixing tank.

[0012] In a preferred embodiment of the plastic processing mixer of this utility model, an electric motor is installed on the top of the mixing tank. The electric motor is located on one side of the rotating shaft. The electric motor and the rotating shaft are connected by a belt. The output end of the electric motor and the top of the rotating shaft are both fixedly connected to pulleys. The belt is connected to the electric motor and the rotating shaft through the pulleys.

[0013] In a preferred embodiment of the plastic processing mixer described in this utility model, a feed inlet is installed on the top of the mixing tank.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model, by providing a driving component and a lifting component, allows the motor to be started during use, driving the eccentric wheel to rotate, which in turn drives the stirring paddle B to rise and fall along the inside of the chute. The eccentric wheel also enables the stirring paddle B to rise and fall, thus allowing for thorough mixing of plastic granules. This further solves the problem that the height of the existing stirring rod is not adjustable, which leads to low production efficiency.

[0016] 2. This utility model, by providing a U-shaped plate, a scraper, and an anti-settling plate, allows the scraper to remove residues from the inside of the mixing tank during use, and the anti-settling plate to prevent sedimentation at the bottom of the mixing tank. Furthermore, the synchronous rotation of the U-shaped plate, mixing paddle A, and mixing paddle B enables the plastic raw materials to be mixed more evenly. Attached Figure Description

Detailed Implementation

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] Reference Figure 1-5 This is the first embodiment of the present invention, which provides a plastic processing mixer. The plastic processing mixer includes a mixing tank 1, a discharge pipe 2 installed on one side of the mixing tank 1, and a valve 21 installed on the top of the discharge pipe 2. A rotating shaft 4 is rotatably connected inside the mixing tank 1. A ring array of stirring paddles A41 is fixedly connected to the surface of the rotating shaft 4. A stirring paddle B42 is movably connected inside the rotating shaft 4 and located on top of the stirring paddles A41. A lifting component 43 is provided inside the rotating shaft 4.

[0029] The lifting component 43 includes a groove 431 formed on the surface of the rotating shaft 4. A lifting block 433 is movably sleeved inside the rotating shaft 4. One side of the stirring paddle B42 extends into the interior of the rotating shaft 4 through the groove 431 and is fixedly connected to the lifting block 433. A lifting rod 432 is fixedly connected to the top of the lifting block 433. The lifting rod 432 extends to the top of the rotating shaft 4 and the mixing tank 1 and is movably sleeved therewith. The top of the rotating shaft 4 extends to the top of the mixing tank 1. A driving component 45 is installed on the top of the rotating shaft 4. A spring 434 is fixedly connected to the bottom of the lifting block 433. The bottom of 34 is fixedly connected to the inner side of the rotating shaft 4. The driving component 45 includes a support rod 451 fixed to the top of the mixing tank 1. An eccentric wheel 452 is movably connected to the inner side of the support rod 451. A motor 453 is installed on one side of the support rod 451. The output end of the motor 453 extends to the inner side of the support rod 451 and is fixedly connected to the eccentric wheel 452. A hinge plate 454 is movably connected to the surface of the eccentric wheel 452. The bottom of the hinge plate 454 is movably connected to the lifting rod 432. The eccentric wheel 452 and the lifting rod 432 are connected through the hinge plate 454.

[0030] During normal stirring of plastic raw materials, the motor 453 can be started to drive the eccentric wheel 452 to rotate, and the lifting rod 432 can be driven to rise and fall along the inside of the rotating shaft 4 through the hinge plate 454. This can drive the lifting block 433 to rise and fall, and at the same time, the stirring paddle B42 can be driven to rise and fall along the inside of the slide groove 431. Meanwhile, the spring 434 will deform or stretch as the lifting block 433 rises and falls, so that the lifting block 433 can be buffered during the rise and fall. The eccentric wheel 452 can achieve the purpose of driving the stirring paddle B42 to rise and fall. In this way, the plastic particles can be thoroughly stirred, which further solves the problem of low production efficiency caused by the non-adjustable height of the existing stirring rod.

[0031] Example 2

[0032] Reference Figure 1-6 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0033] A U-shaped plate 5 is fixedly connected to the surface of the rotating shaft 4. A scraper 51 is fixedly connected to the outside of the U-shaped plate 5. An anti-settling plate 53 is fixedly connected to the bottom of the U-shaped plate 5. A motor 54 is installed on the top of the mixing tank 1. The motor 54 is located on one side of the rotating shaft 4. The motor 54 is connected to the rotating shaft 4 by a belt 55. A feed inlet 3 is installed on the top of the mixing tank 1.

[0034] During use, plastic raw materials are poured into the mixing tank 1 through the feed inlet 3. Then, the motor 54 is started to drive the rotating shaft 4 through the belt 55 to rotate, which in turn drives the stirring paddles A41 and B42 to rotate. This causes the U-shaped plate 5 and the scrapers 51 and anti-settling plate 53 on both sides and the bottom to scrape the inside and bottom of the mixing tank 1 to prevent plastic raw materials from remaining inside the mixing tank 1 and to prevent plastic raw materials from settling at the bottom of the mixing tank 1. The synchronous rotation of the U-shaped plate 5, stirring paddle A41 and stirring paddle B42 makes the plastic raw materials more evenly mixed.

[0035] The remaining structure is the same as that in Example 1.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
